@kingsalmon. There is private messaging on this website. We wouldn't post anything publicly. But your attitude is noted - if you go missing, no one will try to contact you or care about your whereabouts. Some friend.
I've only been in contact with one member outside of this site,I have his personal email and know the city he lives in.Even with that,I don't consider that we are on a "friend" basis.We just liked to share experiences and information.
So,if you were really a friend of Geoff's,you would have,at least,some contact info.
My point is that perhaps he doesn't want to be bothered.Ever consider that?
I don't mind if you don't look for me if I go missing.Chances are that you wouldn't even notice,as I'm not a big contributor here.

The diet world has changed quite a bit since this site was more popular years ago.Also,with media platform changes/evolution,a lot of members have just moved on.
For example,a lot of meat based dieters are now listening to channels by Shawn Baker,Judy Cho, and Brian Sanders who regularly feature videos,podcasts,interviews...etc
Then there are the myriad of Keto/Low Carb channels who weren't at all popular years ago.
So,no need to feel so worried if someone doesn't post here anymore.
I'm still here occasionally as I appreciate the raw aspect of this forum.
Anyway,that's my take.
