We've set up a site to use email address as username. However, the recover username/password form is now extremely confusing for our less-than-tech-savvy audience -- I would love to simplify it, so it has no fancy drop down (which breaks on IE for some visitors anyway) and no multiple choice checkboxes -- simply a text field asking for an email address to which a replacement password will be sent. I've tried hacking away at it, but my obvious lack of ajax knowledge and inability to figure out how that chunk of the php is wired is leaving me stuck (simply commenting out the "lost username" checkbox row breaks the whole system).

Anyone already have a similar hack in place, or could something suggest an approach that would work?
