Thank you. It worked partially for some reason.

Plugin:

$only['quiz'] = 'Quiz';
$only['Display'] = 'Flashchat';
$only['Top_Posters'] = 'Top Posters';
$only['top_statistics'] = 'Top Statistics';
$only['vbfavorites'] = 'vBFavorites';
$only['zointstags'] = 'Zoints Tags';
$only['tutorial'] = 'Tutorial';

The ones that did not get picked up are:

$only['Display'] = 'Flashchat';
$only['Top_Posters'] = 'Top Posters';

The prefix are correct for sure.

Edit: prefix must be lowercase.

One more thing, how do I have the groups listed in alphabetical order?
