I know he's not too recent (depending how that is determined) since he passed away earlier this year and probably has not been on the site since the beginning of the year at best. perhaps logins and/or frequency of logins is what I was more concerned about than posts... you're right... posts don't necessarily give much weight other than "activity level" on the site.this noted, I just wondered whether recent activity was working OR maybe how it determines if a member is recent... however, the other question would be the criteria for "recent activity" status for a member.ANYWAY... nonetheless, it's a definitely great feature that allows users to connect locally.
