As mentioned, I'm not in the classroom at present and will be focusing my effort(s) in a personal/professional direction. I'm a member of several skydiving-related and other groups through my personal FB account, but most have a vetting process to be accepted - usually a couple questions about experience and intention. Just for the heck of it, here's one site that may be fun (and even made into a teachable moment)... tune-in to watch my friend Mike Brewer compete at the World Indoor Skydiving Competition in Bahrain this weekend!

I'm sure there are several FB groups with teachers of different content and grade-level, (honestly don't think it occurred to me to search those out while I was teaching, but am sure it would have been a good thing). I've only been a member of one entitled, 'Int'l Teacher Co-Op'... mostly made up of former classmates from my M.Ed. program:
