Yahoo says opk board is under review. Not sure when they EVER get things fixed but I noticed that on Monday's our
resident Robo must have therapy or something since he is absent for a few hours. Yahoo is acutely aware of the problem, this is one of many message boards that this cyber attack is trying to shut down. Keep sending yahoo messages by scrolling to the bottom of the message board page. Google yahoo customer service for the 1-800 numbers, In time they will ban the server or servers that are attacking their company.
Patience with a little proactive involvement is the best course.
