Perhaps a solution to new users "running out" of posts on small things like declaring interest in an rp would be to add a system where the poster of an interest check can see who is subscribed to their post? That way the x posts per y minutes wouldn't be wasted on saying they're interested, and could instead be used for asking questions about the rp, posting sheets, etc.

This might be making it too complicated though, when a finetuned x per y system would probably work fine in most cases :lol
