How To Display Data Based On A Group
 

I am trying to add some hacks in however I only want those tables to display to admins or moderators.
I know i need a php if wrapped around them however I can not find anything that helps me work out what group a user is in.

if user in Admin or Moderators then blah else nothing.

Any help would be greatly appreciated

if(is_member_of($bbuserinfo,6) OR is_member_of($bbuserinfo,5) OR is_member_of($bbuserinfo,7))
{
// code
}

Thanks rake!
