Doug, put the word wink in these brackets: [ ]. I'll use the word blink (otherwise, it would just become the emoticon): [blink].
Quick lesson: for colors, you do the same thing, but you have to add the step of ending them, and you do that with a slash:   /. I'll use brown, because it won't actually change the color of the text you want changed.
You just put [brown]the text you want changed[/brown] and finish your sentence.
You start and stop italics (put i and /i in the brackets) and bolding (put b and /b) the same way. But do check yourself; if you put [wink[, for ex., it won't work; and if you forget to end it, then your text will be color-changed or italicized, etc., to the end of whatever you've written.
