Are there any other online sites with much less fish?
I hear PokerStars and UltimateBet have their fair share of sharks.The Party skins and PacificPoker have always had some of the softest(but suckouts-iest) games on the net.

I am now back to my initial buy-in with online poker, and I am quite sure that I am going to cashout for good.
You're going through what I'm going through right now.I'm essentially back to my initial buy in(if I'm lucky) and I know that it's tough but sometimes you do need to languish at a level for a while before moving back up.
