[L1keee]

Сделал команду /pm

if(strcmp(cmd, "/pm", true) == 0 || strcmp(cmd, "/ot", true) == 0)
	{
		if(PlayerInfo[playerid][pAdmin] >= 1)
		{
			tmp = strtok(cmdtext, idx);
			if(!strlen(tmp)) return		SendClientMessage(playerid, COLOR_WHITE, "{F74848}» Ââåäèòå{FFFFFF}: /pm [èä] [òåêñò]");
			giveplayerid = ReturnUser(tmp);
			if (IsPlayerConnected(giveplayerid))
			{
				if(giveplayerid != INVALID_PLAYER_ID)
				{
					GetPlayerName(playerid, sendername, sizeof(sendername));
					GetPlayerName(giveplayerid, giveplayer, sizeof(giveplayer));
