I've never tried, but if I were to try i'd do:

pawn Code:

public OnPlayerConnect(playerid) 
{ 
     SpawnPlayer(playerid); 
     return 1;
}

Then handle your dialogs BELOW the SpawnPlayer bit, when you have spawned them maybe toggle them uncontrollable and set them way above the map somewhere so they can just see the sky, then do your dialog thing. Once thats all completed set their Spawn information variables and then SpawnPlayer where you want them.

That would be my attempt anyway.
