Hi!
For my site, I would like to be able to post a topic and when I choose more than one term for it I want it to be submitted to all those forum(term)s. Now all the chosen terms are shown in the top right corner of the post but the post itself is submitted to only one of them. True that a topic can be associated with more than one term, but I want users who browse the different sections of the forum to be able to find topics that are relevant to those forum terms listed directly on all the forum/id pages too.

As applied to this forum: if I decide that my post could be relevant to "post installation questions" AND "usability and accessibility" at the same time, I could cross-post by marking those terms in a multiple selection box.

So, what I need is a way to extend the functionality of the current multiple selection box. By marking more than one term, a post would not only get associated with those terms (and have them appear as links in the top right corner of posts), but it would also get listed under both forum pages.

Also, if I allow multiple vocab terms for a node and I check "required," I am still able to NOT choose any term and still submit my post. Is this the expected behavior?

Thanks.
