Create User Signup Email Hosting script

Create User Signup Email Hosting script I want to use RoundCube. web mail. I want you, to create a script / system so Users can signup for an email automatically. Users need to have a choice of their username. Users will get to choose from a list of multiple domains to use for their email address. eg. @[login to view URL], @[login to view URL], @[login to view URL] @[login to view URL] I would like this in AJAX, so that it looks nice and the users chosen name will show red or green. Red if taken, green if available. (or symbols) Thats it!
