How about adding an entry to the FAQ for this Message Board that shows how to do some of the special formatting. I have seen a few threads where these items are discussed, but then when I want to use them, I have to hunt for the location of the thread that had the info in it. It's pretty easy to use bold and underline, but some of the other things aren't quite so strait forward.

Like adding non-standard smileies.

I don't know how to make RED text.
Is it like this RED?

There are probably lot's of other things that can be done also, and having them in an easy to find location would be helpful.
