Alternatively do a search on google to find sites which track the freerolls
on several different poker sites
, which can be handy if you want to play a freeroll at a given time... if you want frequent, small freerolls, then you could try PokerChamps or Absolute Poker. If you want big, regular freerolls, then try the Prima network (e.g. 32red or Battlefield Poker).
Starting threads just to ask a question that's been answered many times before is an annoyance, because it clutters up the forum, making it harder to find the existing answers and other information. Before starting a new thread with a question, check if it's already been answered - because it's just lazy to expect others to do the leg-work when you can't be bothered to do it yourself. Before starting other threads, it's also worth checking if there is a closely related thread already - no point in starting a 2nd thread on the same subject unless the focus is sufficiently different.
