For me, it's just facepalm. They let you use special characters in your password while signing up, and then don't let you in cause you are using special characters.

Ok, let's reset the password then. Filling in the form, clicking on captcha - email was sent. But looks like it wasn't. Have not got any letter from them, checked the spam folder of course.
But the "Username Reminder" letter comes instantly.

The funniest thing is when you click on "Support", they want you to sign in.
