Removing the "powered by VBulletin" when saving as a favorite
 

Should be simple really but i can't work it out.

When users save the forum site as a favorite, by default it comes up as...

xxxforums - powered by VBulletin

Even if you save the link as just xxxforums, when you hover the mouse over the favorite is still comes up as xxxforums - powered by VBulletin.

How do I get rid of the "- powered by VBulletin" part??
