If you know how you want to save it, just do like:

pawn Код:

new startnote[126];

//do a command just like normally then set this function in there.
new writethisnow[126];//sscanf or something to detect and save what the player writes after the command part.
format(startnote, sizeof(startnote), "%s", writethisnow);

//and on player connect just use 
if(strval(startnote) != 0){
ShowPlayerDialog(playerid, 18273, DIALOG_STYLE_MSGBOX, "Important notice", startnote, "Dissmiss", "");
}

Hope it helped
