Poker Ettiquette
If there is one thing that I feel is completely in poor poker taste is when someone has checked intially then when someone else has made a bet, they suddenly decide to raise the bet. Poor taste for all those people out there who do that.

Poker Tournments
I hate it when I am trying to enter an poker tournement on my favorite sites and I can never get into the tournament because the site does not have enough tables open.
