Approximately six users may have been affected with a bug in the donator CP that caused their passwords to be invalid. I upgraded the security on some parts of my system, and these users created accounts during the upgrade. If you are experiencing this problem, reset your password using the password reset form:

The site no longer stores your password and uses a password hash + salt instead, so instead of being e-mailed back your password, you get a token to reset your password instead.
I also changed the “log in” link on the top of the site, I guess it was causing confusion for some as it logged users into my blog instead of the donator CP.
