why would yahoo messenger sign me out, saying that I've signed in somewhere else when I have never left?

yes, the messenger is down!

everyone is facing that problem,

everything is wrong about yahoo! messenger right now, no ones messenger is working, so don't bang your head on your computer screen in frustration! :)

yeah, i have a similar problem too. i thought my internet provider sort of blocked it because it displayed a message about the yahoo messenger but i ignored it and then there it is i can't sign in to yahoo using the messenger now. im glad we also share the same problem. hope they fix this thing at once. the new yahoo messenger is so buggy they should not have released it immediately. and also that crazy add below the messenger, don't you think it's an adware? does anyone know how it could be removed? it's quite an eyesore.

Yahoo is experiencing server difficulties

They are working on it, they should be up and running soon

This has happened before....

Yes, i know it sucks :o)
