If Volunteer Joins an Interest Category or Registers for an Event, then Add to Group

Hello!

It would be helpful to us to have the option to have a user automatically added to a group if they register for a specific event or if they add an interest category to their profile.

Our use has Group Managers who both manage a set of events and contact their group. As it stands now I have to manually add people who set their interest categories to the associated group. If I do not, then the Group Manager is unable to contact all of the volunteers who are interested in volunteering for them.

Thanks,

Tony
