I need an AJAX-based signup form for listmessenger, a popular PHP newsletter program. Currently, when a use signs up they are taken to a separate page within the newsletter directory for any kind of success, failure or other messages. I'd rather keep them on the page they are currently at, so if these messages could be displayed via asynchronously that would be great. The fields I need for the form are Email, First Name and Last Name. If one of these are filled out incorrectly, it should state that asynchronously. If everything is correct, a success message should appear. You will need a webserver and will need to install listmessenger yourself so you can do the dev testing.
