Validate Usernames Before Registration
Carl Crawley had a recent project that required the username be checked before the member registration form was submitted by the user. We’ve all seen this (Twitter is a good example) before but Carl made it happen with jQuery and the Query module.
Carl uses the Query module to do the actual check and jQuery to submit the data for processing. Very nice!
This is a technique you’ll probably want to use at some point, so be sure to bookmark it: ClientSide Username Checking, EE and jQuery

I have made the same for expressionEngine, also with jQuery: http://www.citroen-forum.com/mycfcom/sign_up/
