By "Private", it just means that only group members can see it, not all Facebook users. Of course, all PSSA members who use Facebook will be able to join the group. It could set to be a "Public" group, which would mean that all Facebook users could browse it, although only members can post to it. Initially I've set it to Private as it seemed more appropriate.
As we have no idea how many PSSA members use Facebook, I think we should give it a go. I think we're more likely to get news and photos on there than we ever do on this forum. And Facebook has the advantage that posts are brought to your attention - whereas we know 90% of members look at this forum less than once a month.
It certainly isn't about creating a private clique; if anything, it's the opposite. Those of us outside the Solent don't get much of a feel for what's going on; event reports are rare and slow, whereas Facebook is immediate.
But yes, rally info will still be on this forum, and the photo gallery on Flickr, both open to all.
And I like the idea of having a precis of forum topics in the newsletter.
