I have started a Facebook group to more easily share lunch information and so we can share work and announcements more easily.
Ideally, I hope to eventually eliminate the weekly email in favor of this but the snag is not everyone on the lunch list is on FB.
To start a group I had to add people, but I do not have time to add everyone, so join yourself if you are interested.
The group is closed, so you can share work that you may not want seen by your general feed.
I also plan to do a weekly event for the lunches so people can RSVP so there will be less of a problem if people cannot find the group.
