Chip sent his portfolio along with his "take" on the economy and the why of his decisions via email in adobe format. Some of us were receiving this for several years. He also contributed to this forum as well as the diehard forum.
I hope he and family are well but his style, IMO, would not be to drop out like this if all were normal even if he were going to change his newletter to fee based... he would just say so, I think. He did travel out of the country for extended periods and possibly he is traveling now and his computer isn't available.
Bottom line I don't think you can get a copy unless he returns.
