Right now I have this memberlist_complete plugin in 0.04.1 which will be released later today:
// Insert Members List - Chosen not to be listed
$fake_members = $vbulletin->options['fake_stats_members'];
$fake_members = vb_number_format($fake_members);
$totalusers = $totalusers + $vbulletin->options['fake_stats_members'];
$totalusers = vb_number_format($totalusers);
which shows on the left the phrase one has to manually add in the memberlist template, and on the right it will show 'showing results 1 of 2 of fake_new_value
This way it won't say on the left '5000 chosen not to be listed' and on the right 'showing 1 of 2 of 5 ..' should be at least 5000 + 5
I've also applied the vb_number_format which rogersmn was missing .. I tried to update the template cache so no manual template edit was needed but couldn't get it to work. sorry
I will look into the spreading of fake values over multiple forums, but i simply won't have time today. cybernetec if you know how to do this please write out instructions and i will update the plugin.
