The Interests module allows a club or association to list and describe various special interests, programs, or affiliations the organization sponsors. Interests are grouped into categories that each group also defines. Members can then register for an interest from the Interest pages or their Profile screens.
If the interests are based on what members like to do, they allow people with similar experiences and desires to meet and share experiences. If the interests are based on organization activities and programming, they provide a ready group of participants and volunteers to ensure the success of an endeavor.
Committees are formal subgroups of members that think of interests as informal subgroups of members that grow and shrink over time based on member preferences.
Interest categories can have a coordinator responsible for managing that interest and the underlying activities around that interest. You can also create a discussion forum around an interest, and forum membership will be automatically maintained as interest members come and go.
When the Interests function is enabled and placed on the menu, members can sign themselves up for an interest and remove themselves from an interest by going to the Interests module and clicking the appropriate buttons. They can also click Profile – Interests to check or uncheck multiple interests simultaneously. Finally, you can configure this profile page to be part of the Member Signup Wizard so that new members can select their initial interests during the member signup process and update them during the membership renewal process.
Administrators can email members of an interest group from the Interests module and the Control Panel – Emailings option. With the visibility options at the Interest Category level, you can use this module to create ad hoc lists within your club or association that are visible to admins only.
