$userinfo[pmlink] ?

okay, so i'm making a graphic free template, on the online list, there is a graphical link that allows the user to pm another user. I went into the "Who's Online Templates" and into the "whosonlinebit_pm" template. and found the following code:

<td bgcolor="$backcolor">$userinfo[pmlink]</td>

that is obviously directing me to antoher template, which is in a category entitled "userinfo" .

Well, i went through every template in vBulletin, and I just can't find it.

Can anybody assist me in locating this template, so that it contains a textual link, and not a graphical link .

Thanks
