Why does Treasure-Search recommend you provide an email address; but not 'require' it?

So that if you forget your password, we can email you a new one.

Otherwise, there's no way we can know for sure, someone who tells us they "forgot their password", is really you!

Be aware though, that if we don't have your email address and you forget your password, then we can't help you. The only thing you'll be able to do at that point, is to start over with a new username!

So, let's just say ..... it's highly recommended.
