Hey when people leave OR quit a site its no BAN. Think its rare some regular user leaves permanently & never peeks in
after months or few years.
Especially if those users such as TMS had pretty good diplomatic relationships with others on forum board.
Many folks may come back at some later time with the same HANDLE or different handle.
Call it simply taking a break. When topics get heated to take a break from site discussions is best for both sides involved.
Hey they chase me off MSG boards all the time in the past. Even had individuals whom wanted to meet and take up gripes face-to face.

Anyhow respectively
