Stay off it if you have any sense. It's addictive. Folk can't go to bed, or are checking their phones in the middle of the night.
To be truthful, I only started it, with a load of my own photos and then left it alone for a while. We had about 100 members last month, I posted something, which prompted a friend to post an old film he had done, a few people invited their friends and now we have nearly 1400 Members.
For 10 years, on RRO and The Gob, I've tried to get folk to dig out their old photos, before it's too late and nobody can recognise what they are. Even worse, old relatives die and their photos go to the tip! This Group has finally done what I wanted. There are the most amazing, previously unpublished photos coming out.
One or two have posted scans from Anthony Page's books but there aren't many and they do illustrate topics, if there are any complaints I will remove them but it isn't for profit and it is all about sharing memories.
Swearing and Smut have zero tolerance and offending Members blocked

Just because you're Paranoid, it doesn't mean to say they're not out to get you.
