Add a new user group to your concrete5 site. Your group's name and description can be used to help organize users into easily-managable roles and responsibilities.
Group Expiration Options
Groups can be set to automatically remove users after a certain date, or after a certain length of time has passed. This option is handy for setting up "trial" accounts, or any other scenario when you want to limit the amount of time a user has access to certain parts of your site.
Users can simply be removed, have their accounts deactivated, or both.
