Hmm. I am not honestly sure how we could, because if we put it in Free RP we'd have too many people not taking us seriously. If we put it in Spam it would be derailed within moments (I have poked my head in there before and nearly gotten it bitten off for doing so!) I don't think we could put it in Casual, since most people would be posting one or two sentences, max.
So... That leaves Roleplaying Discussion and Off-Topic. I'd think we could put it in the RP discussion category, personally. But... How to still attract people. Hmm.
Well, links in our signatures? Haha. But really.
I don't know. My creative muse has gone kaput over the last three hours.
