Personally, I think a modified version of the calendar (something along the lines of the hack I posted a link to earlier) would work great because it has the ability for a more organized response ... however, users (not just admin) would have to have the ability to post an event for it to work correctly. It's hard to make heads or tails out
that mod because of all the "fixes" provided to an unsupported mod.
Having said that, yes! a forum could work as well.
As I said, this might be able to be accomplished by cosmetics with the ability to add a link to the vB Chat interface. But since vb.org insists that even add-ons include some change to the code, it would seem to be up to you to provide this option for those who would have no idea how to tie it all together.
And as for "correcting you" ... that ain't gonna happen, my friend. After all ...
you da man!
