I'd like to add a suggestion to this. On Facebook, you can choose to create an "Open Group" or a "Closed Group". With an open group, anybody and everybody can go on your page, read and see everything that's even been posted. With a closed group, only members who have been approved and added by the page's administrator can post, and only they can read the posts. If it comes to using Facebook rather than the forum, I would suugest the closed group. This way the whole world doesn't know who's away on vacation, or gone off for the weekend, etc. For everyone's privacy and safety, that would seem like the better way to go.
