Multiple 'Forums' Under One Roof

[?J?stMe?]

I apologize if this has been posted, I searched for what I thought would be good keywords, but found no answers.

In our forums we have several distinct groups of people that would like to have subforums with their own 'look and feel' (themes / skins / etc). I want to share one user database and have things like bans, etc global across the entire domain too.

Basically I just want to have everything tied together under one domain, but give those users the ability to customize their subsection to their liking.

Perhaps this is just done by way of themes and skins that those users pick, because I know you can already set up subections upon subsections for whatever you want. I just want to give those user groups some more latitude to set up their sections and so on.

I am looking for something like here

Is anyone else doing anything like this?

Thanks much all.
