For those that are wondering about members that we haven't heard from for a while... if you click on their name (on the left) in any of their posts... you'll see under the Active Stats the date he/she was last active. That's a date and time based on login, not when posting. So that should help. If you can't find a post, click on the "Members" up on the right-hand side (top of any page). You'll need to search for his/her name, but it's easy and then by clicking the correct name you'll go to his/her profile.
And yes, we do want to respect everyone's privacy. But it's still nice to know we all look out for each other because this is a community of good, caring people
