If i try to login with my account, i get "Invalid email. Try another one." error message, while i'm using the mail from the activation email, and what i could use before the update of the site few months ago. Probably it's because the address looks like this: something+another@mailservice.com. Which is a valid, and working mail address, and it's valid by the email address standards too, however many validators flag it as invalid.

Please fix this, so i can log in again. BTW adresses like something.thing+another@mailservice.com are also valid.
