Username or EmailPassword
Years ago I tried PC-BSD because it seemed really cool. The installer was way more advanced and far easier than Ubuntu's installer, even now. I always wanted it to work and this was back when I was considering a move to the BSD's. But with PC-BSD there was always the problem of the password. I would enter a tough password consisting of letters, numbers and special characters and I would use around 18 to 20 characters. Then once I made it to the login screen the password would never be accepted. Even if that was no longer the case I would never leave Ubuntu nowadays.
