I read a blog by a newbie this morning and decided to address the question about private tourneys with or without passwords. 

Many poker sites offer freerolls with no strings attached and some offer a private freeroll here and there, that you have to know the password to be included in the tourney.  Most forums like Poker Curious are hosting these private tourneys to give back to their members.  Now the word private means just that.  The password is for members that attribute something or sometimes nothing to a site/forum in return for a chance to make a bankroll and meet new people. 

I will describe Fulltilt Freerolls since this is the primary site I play. 

FullTilt Freerolls come in two types, those that are open to the public, and private freerolls that are only open to those who have the password. Most of the private tourneys have information in the lobby on how to get the password via web link or some have the password in the tourney lobby. (Very few have the password listest, but some do)  The public freerolls tend to be much larger fields and less money to be made, but there are lots of them. Some payout in Tournament Dollars and can be used towards other Real Money tourneys.  Look under Tourney tab with Play money selected and you will find one freeroll about every 4 hours. There is a registration time usually about and 40 minutes to 1 hour before tourney start time.  These fill up pretty quick. Hope this helps with the question about freerolling.  GL. X
