Muck means you dont show your hands to the oppenent if you lose on a check/call or if you win with everyone folding you just muck them (dont show) which is obviously advised.
Alien you were saying about freerolls being quite pointless, i can see what you mean but I dont want to put any money out of my account as im far better in the face-to-face games and i won £50 last week through it, bloody spent it in one night mind.
However in these freeroll tournaments when you do get far and win a prize after entering for nothing you have something to use to go into these cash games. Example, i won a
Paddy Power freeroll and got a massive $8 for it. Now theres something for me to use instead of funding my account with my own money. Although relative your right you would prolly earn more flipping burgers per hour put it. Difference is i enjoy Poker and im a lazy sod.
From that $8 its gone up and down and im on $11 after a few days playing with it and im quite happy to use freerolls to fund my playing. I usually play them at
Absolute Poker all day when im not out in order to get some funds into that account and start playing there, no such luck there though however after coming close many a time. Freerolls have a sort of lottery about them as you point out but once you get into the latter stages and the numpties are out its a better game.
At the moment im having fun just doing this with my $11 profit at the moment

and my profit in non-online games of £50 which I intend to keep seperate as its earning me some valubale money, always play people of lower standard of course and cos there my mates there too comptetetive and will put it down to luck that i won that much money off them. When i have money to my name i will start playing serious but until i stop being a lazy bastard that wont happen yet.
