Yep, gotta agree...there are so many side boards, I'd probably just rather stick them there. Then again I get a little sour when people post a new thread for each miniature they post...
So I'm just a crotchety old bastard.
Now, it's possible you could start a "post your dioramas" thread in say...Other Adventures or Workbench section and keep everyone in one thread. I prefer finding a quality 30-page thread than dozens of disparate threads covering similar stuff.
