I think I’ve been through this a couple of times myself:
Sarah A. Hoyt has a fine rant about accursed petty bureaucrats. I tried to leave a comment telling her what I thought, but WordPress wants a password. My browser remembers the password to every other website I have ever visited, but not WordPress. Fine, make up a new password. Sorry, you’ve used that one before. Try a different one, same response. Finally write a sentence full of cursing and it accepts that one. Doesn’t matter, because whoever is in charge of remembering passwords will surely forget this one as well.
I don’t have a perfect record at password retention, but I don’t obtain them via rectal extraction either.
