Question about User Group Management

[Been Told_]

I have a question about user group management.

 

What I would like to do is:

 

- I create a user group.

 

- I designate a member the "moderator" or "head" of that group.

 

- Other members may apply for membership of that user group.

 

- The Moderator/Head of the group can approve or deny those requests.

 

Is that possible out of the box? And if not, is there a mod that does this?

 

What I want to do is semi-recreate the social groups discussions that vBulletin has. Only I would be doing this with user groups and actual forums.

 

I am aware that there is a plugin for IPB 2.3 that does this (sort of), but it has not been updated to 3.0 yet and I would be willing to sacrifice the "automation" that plugin may offer, for the possibility of doing this out of the box.

 

I really don't want to install too many plugins/addons.

 

Thanks in advance everyone. :)
