any info on this thanks.

Thanks Daisy, i ended up using this  

 $isModerator = OW::getUser()->isAuthorized('base'); 

assuming all moderators will have a minimum of base authorization.

Yes but this does work for me because base is the default, all moderators for me will have the minimum of base and more if necessary.   I am using this for the IP tracker plugin.  Because i want my moderators to be able to see the IP and check the ip before approving.  So this works in my case.  

The reason i had to do i this way is because isModerator did not work, it gave me a invalid method which surprised me because i thought the BOL and dao and common primary calls were basic to all plugins but i guess not.

Thank you daisy for your assistance :)
