Moderating Function?

[Logikos]

I was wondering if there is a function to show if a user is a moderator or not. I want to update a hack of mine. The old code is below:

PHP Code:

if (
        $vbulletin->userinfo['usergroupid'] == 6
                OR $vbulletin->userinfo['usergroupid'] == 7
                        OR $vbulletin->userinfo['usergroupid'] == 5
    )
        {
                // code here
        } 


Is there a function so i can clean this up some?

PHP Code:

if (can_moderate())
{
        // code here
} 


Something along those lines maybe? Thanks guys!
