I can't believe I didn't know GPT existed until a few months ago.... I was able to quit my waitressing job and stay at home with my one year old. The following sites are great, I especially like RainingRiches, the site owner is awesome. I've joined probably 25-30 gpt sites, and these are my favorites. Good luck, I hope others have as much fun with this as I do.
