Sharing a few sections on different boards
 

I did a few searches on this and came up empty.

I have two related sites that would benefit from a few shared sections. I do not want the same sites duplicated with different urls. I want to share only a handful of sections across the two sites.

There are some inherent difficulties such as problems with duplicate usernames if I leave the current individual user databases. I could either attempt to combine the user databases or figure out another method to show which forum the user is posting from or something along those lines. The best long term solution is probably to combine the user databases.

Assuming the the duplicate user situation can be worked out is it possible to have two individual vB sites sharing a few sections so that posts from either site show up on both (or more) sites. All would have a valid license of course.
