Cbox VS Vbulletin

[Winter Sonata]

Hi there , I want to ask how can I integrate my forum's users to use cbox shoutbox, I mean only registered users can use Shoutbox ....

I have read the faqs there and it says

1. Log in to your vBulletin Admin Control Panel.
2. Choose Plugins & Products -> Add New Plugin from the menu.
3. Create a new plugin at 'forumhome_complete' and insert this code:

$cbox_nme = urlencode($vbulletin->userinfo['username']);
$cbox_key = md5('1.................' . $vbulletin->userinfo['username']);

4. Save.
5. Locate your Cbox HTML code in your forum template.
6. In your Cbox HTML code, find: sec=form and immediately after, paste: &nme=<?=$cbox_nme?>&nmekey=<?=$cbox_key?>
7. Save.
8. And finally, click Enable lower down on this page to turn user integration on.

But it doesn't help ..... even send them a suposrt ticket but till now no answer yet.

Could you please help !
