Just expanding on what Nanako had suggested with a side suggestion:
Seeing how that the threads regarding requests and claims are backed up anyways for reasons already stated, perhaps it may be a good thing to is to set a date every week that whoever wants to work on the name changes could regulate. Like, every Saturday, all the name changes from the previous week would be done. That way people won't be going "Change my name! Change my name pleeease!" to those who work on those. They would know that name changes aren't done until Saturday for example. You know?
That's fine and dandy in all, but then you would have people who don't read the rules would still be bugging people. Just like the people who keep asking when they can get their name changed, even though it says how long they have to wait on the first post.
I really need a new signature.
