How to add 'Activation Code' cell to the navbar for usergroup 3

[Mazinger]

How to add a cell 'Activation Code' in the navbar for group 3 (users awaiting email confirmation):

In Navabr template:

Search for:

<if condition="$show['member']">
   <td class="vbmenu_control"><a href="login.php?$session[sessionurl]do=logout&amp;logouthash=$bbuserinfo[logouthash]" onclick="return log_out()">$vbphrase[log_out]</a></td>
  </if> 

Add after:

<if condition="$bbuserinfo['usergroupid'] ==3">
<td class="vbmenu_control"><a href="register.php?do=requestemail">Activation Code</a></td>
</if> 

You may change Activation Code to whatever you want...

I tried to use $vbphrase[activation_code] instead of Activation Code, but that didn't work.
