The actual fields that appear on the first page for volunteer opportunities, and whether they are required or not will vary depending on how your organization has set its requirements.  So not all feeds described below may appear in your portal.  If any field is shown and not mentioned here - ask your system administrator for an explanation of what the field is used for by their organization.   Here are some of the major fields that will appear:

The fields will also vary depending on the schedule type and registration type of the opportunity you defined:

The red * indicates that a field is required.  Most fields are self explanatory or have a green ? help icon which provides further explanation.

1. Opportunity Name -  (the name of the opportunity as you wish it to be appear on the website. Good clear names make a difference!  (i.e. "Arts and Crafts with Kids" is a better opportunity name than "Volunteers Needed"
2. Schedule Type and Registration Type - see this article for a full explanation on the four types of opportunities that can be created based on these two characteristics.
3. Description - this is the text that describes the opportunity in detail.  You can use the WYSIWYG editor to style the text (very similar to how you would in a word processor), and can even upload and add images.  Keep things as simple text unless you're somewhat familiar with working on website content.   But its a powerful tool if you are familiar with creating html through a web editing tool like this WYSIWYG editor.
4. Opportunity Coordinator - select the name of the member of your staff (usually you!) who will be in charge of the volunteers, confirm their participation (if using 'express interest") and report attendance after the project.  (If you need additional staff members to be opportunity coordinators, you can request that they be added as opportunity coordinators using the My Organization / Create Organization Contact option.
5. Location - A location is the address where the volunteer opportunity will take place. Any location you've created in the past is available here to select, or, if you need to create a new location, select the picklist option "Add a location (next step)".   A location is required for all opportunity types EXCEPT Individually Scheduled / Express Interest Only.   If your opportunity is an IS / EIO and doesn't really take place anywhere, just leave the picklist value set to "Select Option" (you'll notice its not required to make a selection in this field for this opportunity type)

How many of the following fields will appear in your portal depends on your organizations configuration and what info is provided on the website.  

6. Image - if your organization is 'featuring' opportunities on the site home page, you may be asked to upload an image for the volunteer opportunity.  This image must be square.  (It is separate from any image that you may have entered in the project description, and only used in the "Featured Opportunity" portion of the website, if it is enabled.

7. Primary Impact Area - select a value.

8. Population Served - select a value (generally not required)

9. Age Groups Served - By default, "All Ages" is preselected for you - but if your project only benefits certain ages, then you can change the selection here.

10. Minimum Age - what is the youngest volunteer that can sign up for the opportunity?   (Note: In some sites there are two separate age fields.  Minimum Age is the minimum age to sign up,   "Minimum Age with Adult" is a way to say that a young person can volunteer, but only if accompanied by an adult.   If only the minimum age field is presented, the minimum age and minimum age with adult will be treated as the same age.

11. Maximum Attendance - This field only appears for Date & Time specific opportunities. It is the maximum number of volunteers you want to sign up before 'closing' the opportunity to further signups. Any volunteers who try to sign up after the maximum attendance has been reached, will have the option to join a waiting list and be notified is space is available.

12. Suitable for Groups - a search field for finding projects that are well-suited to groups.

13. RSVP/Seniors - a search field for finding projects that are well-suited to seniors and RSVP volunteers.

14. Type: if this field is available, its used to indicate if the opportunity is a volunteer service project, or an "Activity" If you select 'activity' then you'll be asked to specify the activity type.  Activity Types include:  Training, Recognition Events, Socials, etc.

15: Minimum Required Level of Verification:  Nextthis field only appears if your organization has enabled background checks via Verified Volunteers.

16. Next - click the next button to get to the next page of the Opportunity Creation Process

If you opted to create a new location in Step 1 - you'll be taken to a Create a Location page.  Fill out the fields to describe where your opportunity takes place.  The "Special Directions" field can be used to identify any special instructions relevant to the location:

The final step in creating an opportunity is to set dates for it.  The process varies depending on what Opportunity Type you have selected in Step 1.

Because date and time specific opportunities can take place on one or more dates (occurrences), you'll be asked whether or not the opportunity occurs on a regular schedule.

If no, then just enter the Date and Start and End Time.   You can also Create Additional (non-regular) occurrences, for additional dates by clicking on "Create Additional Occurrences".   When you are done entering your date(s), click on "Create".

If you indicate that it has a regular schedule, you can define the type of recurrence (daily, weekly, or monthly), and the date range for the occurrences.  So for example, if I want to have a project on the 2nd Friday or every month from September to March, I would fill in the fields as follows:

This would create separate occurrences for the 2nd friday in September, October, November ..... through March.  7 different dates (occurrences) that volunteers could sign up for to attend.

For this opportunity type you are requesting that volunteers sign up individually, at times when you need volunteers.  

1. Start Date and End Date - this is the period of time the opportunity will be posted, and when you are open to having volunteers express interest in volunteering with you.
2. Day of the Week / Start Time / End Time -- for each day you need volunteers, you can set the time range that they can express in.   Pick a day of the week, a start time and end time, and then click "Add Day & Time" to add it as a schedule item.  You can add multiple days and times as desired so that volunteers will only express interest during the times you need volunteers.  
3. Click Create to finish posting the opportunity with the appropriate schedule of when people can express interest in volunteering.

In the schedule shown below, we want volunteers for any time they are available betweeen 9 am - 11 or 2 pm - 4 pm on Mondays.... and anytime between 9 and 5 on Thursdays.   (Remember: In this opportunity type - volunteers can sign up for any start and end time WITHIN the schedule you've posted.
