Well,

pawn Код:

public OnPlayerConnect(playerid)
{
     your script ..

     SendClientMessage(playerid, 0x33AA33AA, "MoTD : your motd here.");
     SendClientMessage(playerid, 0x33AA33AA, "MoTD : second line of motd if you need more lines ...");
     return 1;
}

motd is message of the day I think
