vB3 One member base, multiple forums

[majglow]

Would this be possible with vB3 templates?

In one vB install create 2 main forums djforums.com and re-forums.com and create all the respective forums in there. Then depending on the domain name, only show the specific main forum and consider that one the main one?

Or, just create all the forums in one big install and only show the specific forums depending on the domain name.

It would be a real drag if we had to have separate user bases.
