I woke up to this news and immediately got pretty upset as Mark and I have been good friends for a good many years. I talked to him in late December or early January so he was alive and well then.
Brad, god knows I hope you are right and he is fine and well and such, if you say you spoke to him then I believe you.
And this isn't impossible to do for him to post on the board, or his nick to post on it. Anyone ever hear of hacked nicknames? That is entirely possible and I have seen it many many times.
Whatever the case, bad health or otherwise, I hope he is all well and good.
