Test the script here.

Sorry, but none of these work.I've tried ALL of the codes for the 'check username signup' code.All you do is type in the box and the words 'this username is available!' and 'this username is unavailable.' ALWAYS appear so you don't know if it's available, or not.I would use this code but i can't because it doesn't work!If you could,somehow upgrade it and make it work.I want one of these but this one is the only 1 i can find-and it doesn't work at all.too bad.
