I don't even have yahoo messenger installed on my computer, or my phone, only inside my email, and I get kicked off saying i'm on somewhere else when there is no where else and i'm unavailable when I'm available. what's that about?
If you have you email open 2 times at the same time...in two tabs...they will take that as if you were 2 people signed on at the same time...so it will kick you off one of them!
