..because InfoWorld magazine decided to revamp their online forums.
They did not pay any attention to the forum participants when they did so, even though we, en masse, agreed that changes were necessary and were willing to help.
They destroyed them.
We wandered to another service provider...that worked for a while...then frustration set in with our fearless admin(and super programmer) and here we are.
So while we appreciate the notice, our group has already been through this and know that your chances of having Yahoo actually care what you think are about zero.
