I'm OK with Facebook but, let's face it, groups.io is a vastly superior vehicle for sharing information, contacting individuals, archiving photos and files, etc., etc. Search functions work great.
I now belong to 7 groups, and they all have something to offer (despite widely differing levels of activity). Accordingly, I just can't see investing any time in Facebook groups. It's hard enough already to carve out adequate time at the modeling bench.
