I've just realized that in each persons "Profile", where is says "member since" & "last accessed" there are numbers (00:00) between the date & year ... those numbers represent the time you joined & the time you last logged into your account.
I couldn't figure out why I hadn't posted in 5 days but it said last accessed today... I finally get it now
Am I havin' a blonde moment or did anyone else not know that either?
