limited access usergroup

[Chadi]

Thanks. I accomplished everything I needed:

- limited access usergroup can only visibly see the member resolution forum
- cannot access any other part of the site

There is only one thing missing and I think this is more of custom work, but I'll ask anyway:

allow the member in the limited access group to only be able to view one specific thread (created for them, where the discussion is made to resolve any issues with that particular member). I know this is far-fetched, but I don't think it should be impossible with some custom plugin (if not possible by vb default).
