Well "Connected to Las Venturas Roleplay" appears normally just before the class selection screen appears. So I would do:

pawn Код:

//Near the top of your script
new ConMessage[200];

public OnPlayerConnect(playerid)
{
  ConMessage[playerid]=1;
  return 1;
}
public OnPlayerRequestClass(playerid,classid)
{
  if((ConMessage[playerid]==1)&&(/*The part that checks if they are registered*/)){
    SendClientMessage(playerid,0xFFFFFFAA,"SERVER: You may now login by using /login <password>");
    ConMessage[playerid]=0;
  }
  return 1;
}
