Freeroll passwords are in a subforum in the freeroll section
https://www.cardschat.com/forum/cardschat-freerolls-31/
For buy-in tournaments, there's a 15 *quality* post requirement.
If you read around in the rules and faqs section, it explains how everything works. And there's a sticky in the password section that explains some things as well. Hope this helps.
ps: I hope you turn out to be one of the good guys 'cause that's a really cool SN you got there
(edit because 'hope you turn out to be one of the good guys' sounds mean and I definitely don't mean it that way!)
