What a palaver. Kept telling me that my user id/password was incorrect, which I know they weren't. Tried to reset password only to be told that the code they sent me was incorrect, which it wasn't, shut the damn thing down and reopened it and bingo, straight in.
Still appears to be something wrong though. I tried to access one of the accounts my mine one should be feeding off, and it wouldn’t load. Everything appeared on the page apart from the actual emails, even when I tried basic view. No time-out or anything.
It then took a long time to return to the Yahoo homepage, and logging into my main account was also very slow.
The post by Hans just sort of confirmed the above!
It is Up & Down.... At the moment it is back Up.........But for how long... It's worthwhile keeping an eye on the graph in the link which I have given above.
