The @ clearly shows it’s an email address. I agree that “www” is unnecessary, but so many people insist on tacking “www” on a web URL that they get confused if it’s not there. I’d say “Go to gallery.mydomain.com” and they insist on putting “www” on the front.
One place to that’s putting up the fight (as of 2005, though) is http://www.no-www.org Ok, fine. It’s really http://no-www.org, but either will work. They strip off the “www,” too.
