This is the first time for me to hear about earning money in chatting. I think it is not allowed when you are in a chat room you can't post or state any advertisement else they will block you.
I never ever heard this before!If it's true then I am the one who wants to make money through chatting.LOL
Ya you could make money chating by asking for donations. Probably the best way would be to get people to sign up for surveys. Personaly i think these methods are saturated by now.
I think there are lots of adult affiliate program in which we you can sign up and they will pay you money every click. so you can chat with those people in yahoo chat room and can convince them to click on that links,,,
