I think we've already had this discussion, but the term we used was "thread killer."

I've said it before and I'll say it again: In real life, I thrive on having the last word, and am loathe to allow anyone else to conclude an exchange. My wife gives me no end of grief about it: "Irish! You always have to have the last word! Just shut up already!"

But here in these discussions, the last thing I want is the last word. I hate posting my comments and watching the thread disappear off the bottom of the page with no response. This has happened far too often.

Here's hoping this is not one more instance...
