I just wanted to say I appreciate the great info and grow threads you've posted up here over the years and I'd be sorry to see you leave.
I don't really have any brilliant advice re. trolling I'm afraid- except perhaps to not take the internetz too seriously- we don't necessarily lose an argument by not having the last word. If we've spoken the truth then truth will often out in the end anyway.
One tactic for dealing with trolls is just to laugh at their bait
Hope to see you carry on posting.
