A word to the wise, Matrix. Try to keep membership between 200 and 400. I ran 2 groups on FB when I had an account there, and our membership grew to a couple of thousands in each. It was almost impossible to keep a constant eye on what was happening. I finally restructured both groups, turned them over to others willing to run them with a lesser number of members, and deactivated my FB account. This forum of yours runs smoothly for the most part, and I have found that you respond with dispatch to any and all situations. I think you'd find that difficult to do with too many members. My experience here has been quite positive for the most part, due to how well you have it structured.
