Yi! I'm sorry then. I have no idea what to do with Facebook. I use it as a place from which to post pictures and for a few games. I have 9 friends on Facebook who are mostly about as savvy on social media as I am so they don't post often either.
I do belong to 2 groups, however, but they don't email me to notify of postings unless I have responded to a post, which is rare. You can "turn off notifications" to stop that problem though.
Good luck! The whole social media thing is so foreign to me and, frankly, I don't care enough to learn how to use it. Never mind a "smart" phone. A phone is for making calls. I have a computer for anything else I need and texting was invented decades ago. They call it "email".
