I don't see how that's different from the way the plugin works right now, which is showing spiders/bots private forums which normally can't be seen. After all, moderators and administrators can see Invite-to-Join social groups anyway.

It would be an added option for those that would like to have that. You could leave it unchecked in the options screen if you want, forcing the forum owner to check it if they want it.

But I could see why you wouldn't want the heat from the more 'hardcore' vbulletin members at the .org site.. lol! They attacked you pretty hard for even the standard plugin.

I appreciate the plugin a lot Komplex - it's been fantastic and works great - thanks!!!
