Welcome.

If I remember correctly, there is a function that checks the user name (it's looking at the user table and temp user table to see if the user name exists. You could use this same function (or just have a new one that does the same check). Wouldn't have to be AJAX, though that might allow a check without refreshing the page.

One thing to consider - some might use that function for malicious purposes (though I don't see what those might be - people come up with all sorts of crazy things...). Then again, they could do the same thing by looking at the member list, if that is available on your site.
