This really should be updated. It could be a very good page.
UNN There are two stages to Multiplayer startup. The first stage where all Init events and Init.sqs are executed, up to the point they encounter either a ~ or Exec command. Form a players point of view, this is the screen where they wait for everybody to green up.
The second stage is executed once the admin starts the game for real.
The reason I mention it is, certain commands will only work during the second stage. So having a link to a page, that explains the process would be handy for updating the script command references, for Multiplay behaviour.
