Subforum for Adventure-Specific Discussion Threads

So it struck me tonight that if we collectively wanted to, we could just flat-out make a subforum where people can make discussion threads for a particular adventure and just talk all they want in there.

I think this would be fun even if it doesn't see a ton of activity. Anyone else have thoughts on why this would be a good/terrible/other idea, or how best to organize the subforum if we add it?
