Awright, I was surfing through the forums, when I came up with the idea:
I want to make a huge kickass guide (not telling you about what, though)...
Actually, I'll just go straight to the Juicy center of the idea: a Guide Sub-forum where WIP's of your guides can be posted, and then edited, and finally moved to guides. I've seen this being used on atleast one other Forum, the DotA forum (DotA-Allstars.com - Welcome), where it seems to work great.
I think this would support members to submit their own written, original guides, instead of pasting ol' copypasta onto the Guide boards.
Cheers.
