... and the matter of fact is that you're comparing DCTP to DCW and they're both two completely different sites altogether, it's like judging to people together which is wrong.
Another reason: When I first joined this site, I didn't know what IRLs are. When I saw them in the chatroom, I read the rules and stuff, but had no idea what it is, until I found the roleplays. And come on, these could no doubt happen to anybody else.
So, having a roleplay subforum would actually clarify what irls are.
