Ask HN: Reddit username bug?

i signed up on Reddit last week (am early arean't i?) - using the username justin_bieber_is_666 which is a 20 characters - here's the problem the Reddit login form for username only accepts 19 characters! - right?

though i know my account exits because i can reset my password (an email will be sent to me saying "...password reset for username: justin_bieber_is_666...")
