Wikia has released an update to the forums functionality to make it more like the Message Wall. The Brütal Forum of metal and badassery has not been used here since the Age of the Titans, but if you'd like to give it a spin, let me know and I'll try to raise the relic to make it happen.
I think the forums are a good place for ongoing discussions among multiple people that might otherwise be stuck on a user's talk page and that don't merit a full blog post.
