When posting a new thread

[SwalyAaron]

I've added this BBCODE https://vborg.vbsupport.ru/showthread.php?t=190900


I'd like it to be automatic with each usergroup, so usergroup 6 has it when ever a member of the group posts, the bbcode is automatically in use "[blizz,] [,/blizz]".


I've seen 2 forums use this automatically so what do you think I should do?

--------------- Added [DATE]1369491044[/DATE] at [TIME]1369491044[/TIME] ---------------

Also I have this plugin that would make this work

if(is_member_of($vbulletin->userinfo,5,6,7))
{
$message= "'[blizz]'.$message.'[/blizz]'";
}

But under which hook?
