I like it. Its fun to change the names to like George Bush, and say "Im an starfish!". Or even, if you hate someone on the server, change their name to Ima Jackass.
But on a more serious note, I like it now, but I think it would be better as an admin only, set the ppls names with the changeidentity command. Kind of like the /disguise from Iban's City RP, but just for setting the name to anything.
