E-mail yahoo sponsors and tell them you won't be using the Yahoo message boards anymore because you hate the new format. Yahoo will listen to THEM when they start compaining about a lot of unwanted email concerning a message board.
It also has 'issues' but greater potential than the new Yahoo board. You sign up for an email account (just like Yahho) then get a screen name and you're off. Once done, it is like the main GOOG webpage i.e. its simplicity is its excellence. Check it out....and send Yahoo a REAL meassage. (Maybe I am an idiout but I added to a thread here because I couldn't figure out how to post a new message after 10 minutes of looking?!)
