Had the same thing happen to me. I asked the mods opinion what to do. One said just let it go. Another said the neg would stick. Just saying . I just turned the other cheek.
Well that's what I did last year - just let it go. But when he posts here, I get irritated and feel as though I should do what he says. But then again..does it really matter? Hopefully he will eventually look back through this not say much anymore.
