Since a lot of us check the boards at work ads with sound are a very very bad thing. the last thing i need is the owner to hear something random blasting out of the reception computer. And the overlay ads, since it could be anything, are also not good since if my boss does a screen capture of astorians.com he's fine but if he screen captures one of these ads that may not be appropriate I could get in a whole lot of trouble and have this site blocked. since i have nothing to do but look at this site and others it would be tragic.
