As a 11 year veteran of these places, some posters have simply vanished all of a sudden and never came back. The question is whether they are dead or perhaps in jail. Or worse, dementia:
These are what I remember, please add to the list as you see fit:
1) Sonny. Decent poster, funny then just got really weird. I am hopeful he is not spacing around homeless shelters mentally distressed
2) 408 Mike. A great long time poster. I believe he is dead from a possible AIDS borne disease or an opiate accident. I hope I am wrong, I liked his posts
3) Felon. Likely jail or a halfway house
