First you're want to
Go to admin panel > look & feel > manage skins & templates > select your skin.
Then youclick global templates and then scroll & open globalTemplate.
Inside the globalTemplate script your gonna search for (crt+f)
Above it add
<li id='nav_other_apps' style='display: none'>
<li><a href="LINKHERE">LINK NAME</a></li>
Change LINK HERE into what ever your link is and LINK NAME into the name of your link, of course.
Add more links if you want but your done.
Dont forget to save after you edit the script.
