I've been a member of SLM for to many years to count.  Yes, it has it's flaws, but it has it's good points also. 
The one thing that has always ercked me ( and this is not SLM, but many other groups too ) is when someone asks for detail photos of a car that was raced 30 or 40 years ago , and then gets pissed off and leaves the group when nothing gets posted for a reply.  WELL guys - there is no such thing as a "WAYBACK" machine.  Unless you want to count Dr. Peabody's. 
I'm sure if any of us knew then what we know now, we would have taken those photos.
