I noticed that too this morning. It was the Invision hosting that was in James Gordon's name, and they were completely unable to contact him. It could be that they are transitioning and it will appear back up with the old content restored - or maybe not. To be fair, although the Ed Forum has gone off a cliff dating back at least to the appointment of Sandy Larsen as a moderator, the older content would be invaluable and worth saving unless one just doesn't think the JFKA is worth discussing at all. After the appointment of Sandy, that became the worst-moderated forum I've ever seen (not just due to Sandy by any means).
I had never heard of Invision, but I just looked at their site. I spend more on golfballs than it costs to host an Invision forum (Titleist ProV1x are upwards of $50/dozen). I never understood why all these supposed JFKA heavyweights went through an agonizing exercise every year about "Oh, my God, how are we going to pay for this???" Is the market for JFKA crap so miniscule that Jimbo and Larry Hancock, et al., can't assume the burden? (My guess is, the answer is yes.)
