Code conditional on member post count

[kh99]

What do you mean by "run some code"? Do you want to check for that condition in a plugin? I think it would be:

if ($vbulletin->userinfo['userid'] != 0 AND $vbulletin->userinfo['posts'] > X)
{
  // run code
}

I'm not sure if you even need to check both, it may be that posts is always 0 or undefined for guests.
