Thank you all for your advice. We decided to write them a letter from the membership committee and just unsubscribe them from the group. It's based on the internet so it's like taking away their membership to the message board in a way. Anyway, we are still waiting for the fallout. I know of one current member that they already contacted complaining about me and the committee. Oh well. We are all so much happier that there is no longer negativity in the group.
Sasha, we have a spot for you now. LOL
