You could use the below in the Admin CP, I am not sure what difference it would make, but you do not have to have the "echo" commands in the URL, it deals with the newer versions of vBulletin:
Code:
makenavoption("Edit","faq.php?s=$session[sessionhash]&action=modify","<br>");
makenavoption("Add Group","faq.php?s=$session[sessionhash]&action=addfaq","<br>");
makenavoption("Add Question","faq.php?s=$session[sessionhash]&action=addquestion","<br>");
makenavselect("F.A.Q. Editor");
Just a suggestion
