Pokemon World RPG is a role-playing game mostly about the Pokemon universe. Anything in the off-topic areas of the forum isn't really something I'd have a primary focus on over, say, a rule malfunction or an inconsistency of information between templates and rules/ guidelines. The excess discussion forums, such as "Free Discussion" or "Forum Games" are really just provided as they are as that extra addition.
Despite this personal opinion though, I can give my light agreement towards having a "Sign-Up" subforum. It would makes things a bit easier, as would an "Archive" for older RPs that have either died out or bare no fruit from their time here on the forum (basically, RPs that weren't popular and didn't get much attention (thus dying out I suppose)). That's just my 1 opinion though.
EDIT: I wonder if the reason that the Forum Games subforum doesn't get much attention in regards to organization is because there are periods in which users sign-up and literally just post there or in Free Discussion. *chin scratch*
