The FB Old Tek Scopes group should nicely compliment this site.
FB is what you make of it. I have mine limited to FAMILY only and not all of them. Think I have 22 or so 'friends'. When I get the occasional invite or request I simply say I'm sorry but my policy is ... And I don't even get too may invites cause my settings are locked down. Limited in that way it's a wonderful way to share photo and videos and stories of interest to family only. I ignore the news feeds.
Now with groupsio searching messages is a pleasure. But had the group stayed on Yahoo it wasn't that much (any?) better than FB. A BIG future groupsio issue is the photo search or lack thereof. Still better overall than Yahoo.
And, must say, I don't quite understand not using FB 'for political reasons'. But that's probably just as well.
