Ah I also have been on the receiving end (I think) but will know for sure when the next comment comes and if it contains the magic word.

OMG, I just realized who the friendly troll is. I actually enjoyed reading his comments and you are definitely right the word "insurance" is in every one of my comments.

I am glad this thread was started, because I never would have noticed the "insurance" thing. Too funny!

Now I see it all the time. He (?) seems to like late postings--so when I get updates on old posts days later--especially if there are three or more in a row-- I can be insured that he's been there!
