playing at work?

Russ, I have a question about playing at work. I don't know how web sits work or web filters so this might be a dumb question. My questions is if you changed anything over the weekend to redhotchess or timeforchess web site that would cause the web filter to kwon that the site is games related. The other 2 web sites were always caught but the two listed have worked until today.

Thanks,
Scott
