This is exactly the kind of thing I'm looking for however, I've had a few problems:

1. When using "online.php" everything is fine and working (formatting of the output text isn't great but that's easy enough to change). However, that's only the case while I'm logged into the boards, if I'm not logged in I get the "Unable to add cookies, header already sent." message. online.php works fine on it's own regardless of log in status, only the including seems to screw it up.
2. Using "online_external.php" outputs results regardless of login status however the results displayed on my page are similar to "Members online: 00, 0, 0, 0, 0, 0, 0, 0, 0. Guests online: 26." This is the case on the standalone page too.
3. I'm still don't fully understand the use of the
   PHP Code:

   "print $show;" 

   instructions, I'm probably a fool but they don't seem to be explained that clearly i.e. exactly which page we're adding this code to and whereabouts on the page it should be added to.
4. One other small request, any chance that when usernames are displayed by choice the names are links to the corresponding users profile (new window)?

Thank you for listening to my moaning
