For some reason every time I try to get into a chat room, a box pops up saying "This request has been denied." I have no idea why, I'm over 18 so that shouldn't be a problem.
Is it possible when you created your account that you did not use your real birth date? Some people do that and then forget what date they gave and the age it makes them. Try another Yahoo ID if you have one to see if you are successful at getting into the Yahoo chat room.
