Sure it is. Just change the line into this:
<br />$postrow[$i]['Extra3'] = ($userextra3) ? "{$config['extra3']}: <a href=\"aim:goim?screenname={$userextra3}&message=Are+you+there?\">{$userextra3}</a><br />" : ""; <br />Now that I think of it, the content of the extra fields should be readable in the template without the extra stuff, so that you can do these things in the template yourself. I did it like this since I didn't want an empty entry if there isn't anything in the field, but giving the option to use both ways would be quite nice. I think I'll update the instructions...
