Why am I having so many problems with my Yahoo Question and Answers account lately?

This isn't just happening to you, it's happening to everyone. It takes at least 2 to 3 tries to vote, the Sorry message comes up when going to the next page or by clicking your avatar, our avatar goes back to the grey block, for some it's giving their old nickname under their avatar. There are tons of things happening, or not happening at this time. Yahoo employees have the holiday off, so the problems probably won't get fixed for a couple of days. Put your cursor on ABOUT then click Suggestion Board. You will see a few threads there about all these problems.
