heh, I like the automatic installer/uninstaller, I think I'ma use it in my hacks as well
EDIT: I don't think this will work properly in postbit. Maybe the postbit_display_start should be modified in the following way:
if (!defined('ALLOWHTML_SYSTEMSETTING', $vbulletin->options['allowhtml']);
if (!is_member_of($post,$groups))
{
$vbulletin->options['allowhtml'] = false;
}
else
{
$vbulletin->options['allowhtml'] = ALLOWHTML_SYSTEMSETTING;
}
Also, you might wanna consider re-enabling allowhtml after signature is displayed, to remove the potential possibilty of conflicts with hacks that use bbcode in custom fields etc.
