I figure one of two things are happening: 1) They're in the process of redesigning the site and don't have time to deal with new assets that don't fit into the new protocol or
2) The site admin had some dirt on the Clintons and has been rubbed off the face of the earth
Just speculation. I, like yourself have been trying to contact someone from the site for weeks, and got nothing from anyone. Hopefully they give us some kind of clue soon.
