This mod will let members of your forum pick a membergroup when they register to the forum. The membergroups that they are allowed to register to are configured by the admin in:
Admin / Registration / Settings / Groups that members can register to upon registration.

ALERT
Version 1.1.1 of this mod has been released. Please update to this version of the mod ASAP because a potential security threat exists in the previous versions of this mod that can lead to a new member joining any non-administrator group. A sincere thanks goes to Rudolf for reporting this issue to me.

Note: Membergroups with any of the following permissions are not selectable to be allowed by the admin due to security risks:

• Administrate forum and database
• Manage boards and categories
• Manage attachments and avatars
• Manage smileys
• Edit news
• Moderate forum members
• Manage and assign membergroups
• Manage permissions
• Manage ban list
• Send a forum email to members

Although the checking is done when the group is selected from the admin panel, so if the permissions are changed afterwards a group with one of those permisions can still be picked if they are on the list for groups that are selectable on registration, so be careful.
