Catman,
Let me add my voice to all those asking you to reconsider. I can't claim to have read all your posts, but I've certainly appreciated those that I have.
I too am appalled by the flaming; can only hope it will die down.
As to the cliques, I haven't seen those posts, but I have to disagree strongly. A short time after my first post, you posted a very nice welcome. While I haven't attended any of the FT get-togethers, your posts make it clear that all are invited, and I certainly feel welcome.
Please don't think your absence won't be felt. Come back - it's just not the same without you.
