First off, welcome to the forums. Second, small stakes is HUGELY profitable if you understand how to play the game correctly. My first advice would be to purchase and read
Small Stakes Hold'Em. Its the bible around here. Second would be to post alot of specific hands. Include details like reads on a player or anything specifc you observe about them. Thirdly, use the search button. If you have questions about bankroll, 2/4 vs 3/6 online, etc, they've probably already been talked about and good advice has already been given. Welcome again.
