Does anyone have any suggestions of on-line jobs working from home?

My sister has been an on-line bingo chat host for over a year now and absolutely loves it! She pretty much just monitors the rooms making sure there's no cheating, bullying and so on. I have thought about following in her footsteps a few times as I have grown to hate working in an office after over 3 years of it! But I have never done anything about it. So now, my sister is trying to see if there are any openings on any of the sites which is great but I am also wondering what other on-line jobs are out there??
