We hope to have some sections of help up on here in the somewhat not too distant future.
Was there anything in specific that you had in mind, or what game/limits/starting hands you wanted?
If something springs up that you are curious about just post the question and wait for the replys.
As some general starting advice that works for any variation, play a lot tighter than you think you should. Its very easy to lose money on bad starting cards. If you are playing online and just starting out then basically don't bother with bluffing. Also try not to call too much, if the hand isn't good enough to raise with then chances are you are better off folding.
Only real good times to call is if you either have the nuts (best possible hand) and you don't want to chase out other people in the pot, or if the pot is large and you have a good draw (usually again to the nuts, no good calling for a flush if you think someone else will have a higher one if you make it)
If you post some more details about where, who etc you are playing then we can offer up some more tailor made answers.
