simple bug:
put in an email address with a dot at the end of the first part, like "test.@aon.at", which theoretically is a perfectly valid and working email address. They can't be entered because the email field refuses to accept the address.

I have two people with such an address and can't send them mails over the drupal site, they even can't register as users. One of them can't change the addres because it's his company address.

Please, could you fix this, should be a small thing. (buggy regex?)
