Yes, this is exactly what I mean:

<quote>If you mean that it checks every word in a line of text and if the word is a nick currently in the channel, then it formats it in some way (see above for types of formatting), then that's a slightly more involved script, though still not too difficult to write. </quote>

It doesn't require typing a colon or anything (like mentioned above). You just type the nick & it formats it in bold, or even bold with color.
