I want to save the form value for a persons USERNAME in a cookie when they are logging into my free e-mail service. So when they come back I can lookup the cookie and write the value for their username back into that spot in the form.

I've got it working for the drop-down menu so that it will change to whatever domain they selected the last time they logged in but I can't get it to work for the username box.

in case you want to see the form I'm talking about it's the e-mail login form on http://www.guavamail.com

Thanks.
