/q is a client command, it won't be handed to the script.

You need to use OnPlayerDisconnect properly.

Код:

public OnPlayerDisconnect(playerid)
{
	if(!INGAME[playerid][LOGIN]) return SendClientMessage(playerid,-1,"not login");

That line, is also redundant as the player has disconnected, so therefore it won't display to anyone.
