Jack,
Honestly it doesnt matter to me if I am locked out of your board. I use the same password everywhere, or a variation of it depending on the rules. Twice at your site, my password did not work.
I couldnt figure out which email address i used to register at your sight (go ahead, correct my spelling VKD
) so i asked you first in a PM to change it and then two or three days later publicly to change it for me. After I posted I remembered it was my real life email address I used and it was easy.
Scrambling someones password seems to me the kind of innocent hijinks you would employ to "troll" people which is the only thing I can think of why it wouldnt work twice.
