I just noticed the string of symbols representing morse code on the TMC site beneath the header and navigation tabs. I found a morse code translator and typed what I saw and it came up with a translation for the following site: HTTP:/SEARCH.4SHARED.COM/POSTDOWNLOAD/-YQ5BHKN/ATYCTDEMANDSSTPROOFRKHTML. I'm not sure If I copied all of the symbols correctly or not but I thought that was interesting. I googled the web site and went to the main page and it was flagged by McAfee as hosting risky material.
