Another major problem I have with password restrictions - how about you make sure your stupid password dialog is capable of accepting the passwords generated by password managers? How about you just test the 5 or 6 most common ones? I hate it when I accept the suggested password from Safari or 1password and the stupid site won't accept it because it used the wrong kind of special character, or didn't include enough capital letters, or worst of all - it's too long.

grrrrrr
