Taking up poker again

About two years ago, I dabbled briefly in online poker, but never really took it anywhere. I opened accounts at PokerStars, Everest Poker, Titan Poker and Betfair, and I think I made about $50 playing mostly limit hold'em at <$0.20 stakes. Then things got busy - I had my graduate thesis to finish and I got a full time job, and so I just stopped playing. Well, the job has settled down a bit, and the thesis has been submitted, so it seems like time to take it back up again.
