Hack Request for Someone who Knows AJAX

[derekivey]

Hey all,

I would like to see someone make a hack that is like IPB's registration system, where it checks the various fields using AJAX. For instance, after a user goes from the username field to another field, it would check to make sure the username isnt taken, and display a check mark image if it isn't, and if it is, it would display an X. It would also check the email fields, to make sure they match, and the password and confirm password field to make sure they match also.

I think this would be a really nice hack.
