My lads and their partners, my sister, nieces etc. are all on FB, no problems. They share photos, stories, jokes whatever. There are settings aren't there for privacy so not everyone sees everything?
Chat forums fill different needs for different people. Some, like Jimmy for example, just want to talk about the footie and nothing else. Others want to talk about footie and will talk a bit of OT stuff, others are all over everything morning, noon and night. That's just 3 different groupings without really analysing. And RHC who makes up an entire group on his own [don't tell him I said that -
he can't see this can he]
