Yeah if you add buy-in tournaments it would be awesome since FTP is one of those bigger site, the chance of password leakers is low.
Making a buy-ins is always the best!

I don't know if you read about my idea about making it so you must posts 3 before the day!
If it's a freeroll you should make that way.
That's will get ride of those that are only after the passwords.
You can also make a private section only visible for active members and posting the password there, only those that are trusted members.
Oh yeah you know what I mean
