I honestly don't care if anyone believes me or not. Feel free to spend a few months tracking down someone who knew him to share the news with you. I'm not going to post personal details here, he was a private person, and I'm respecting that.
OP, I don't think anyone here is saying you're lying, but given that he is/was a pretty high-profile member of the forum, the community would like some kind of evidence or at least a lead on how this can be verified. I never knew TECSHARE's name, and I don't know if anyone else did. A lot of people traded with him, so I'm guessing at least a few members had that info.
I get that you want to respect his privacy, but as it stands this announcement is being made by a fairly unknown member who could be anyone, could have various motivations for making it, etc. So if you have any evidence that wouldn't compromise his privacy (and if he's dead, I'm not sure how much that matters anyway), please post it or PM it to a trusted member who can verify his death.
