you can do it
Dear Sir,
you can do it from your: /include/class.nav.php
find this:
$tabs=array('desc'=>'Knowledge Base','href'=>'kb.php','title'=>'Knowledge Base: Premade');
and here is the explain:
in above code there is('desc'=>'Knowledge Base' rename it for example to('desc'=>'FAQ' this is what showing in tab.
and second thing is: 'title'=>'Knowledge Base: Premade'
this will be appears when you put the mouse on tab rename it for example to:
'title'=>'FAQ: Premade'
that's mean when you put the mouse in tab will showing FAQ: Premade
I hope this is clear if you have any further query please let us know :)
Best Regards...
