Hi

I'm using ajax to check username.

I notice that my ajax script is ok... but if a user make a username that my ajax script say
"this username is already registered".. if i click submit i can go forward...

how can i stop to go forward?...

Hi rushseeker,

I'd probably disable the submit button if he name was invalid.
