I'm not part of this group buy, but have been in his previous GBs.
I don't have any specific info, but I recall from a previous post that he had been dealing with health issues a while back. I'm hoping he's okay. A quick search using his publicly available 'real' name shows no obituaries.
I still believe CH to be an honest and dedicated member of this community, that is why I hope everything is okay.
