"Never argue with a fool, onlookers may not be able to tell the difference." - Attributed to Mark Twain

First off, this is generally a polite and courteous forum. Even "heated" debates manage to stay w/in the bounds of general decorum.

However, all forums are subject to the occassional person who posts for the simple sake of argument or, worse, for the simple sake of getting a rise out of another poster. A person making posts like that is sometimes referred to as a "troll".

The best way to respond to a troll is to not reply at all. Rather, if a post is sufficiently inappropriate, then use the "Report" button on the lower left side of the post.

I thought I would reply so that everyone would know that we didn't consider you a troll!

I'm with you on that.

As you can see, I was a troll-tender in a prior life. I tried to keep potential trolls from becoming actual trolls (which occurred when they got past me and into the net). Alas . . . I wish I'd had a Reply button in those days to make all the trolls go away!!

I believe it's a Report button (not Reply) you were seeking. (I like the "troll-tender" part.)
