[pbmserv-dev] Entirely new question from the new guy

["Michael Hammond" <MCTMike@AbacusTech.Info>]

Hey gang,

   Now that my server runs, I'm trying out coding a simple game just to see
if I can.  The code compiles, I can successfully initiate a challenge and
see the startup boards, but when the first player sends the first move, the
program returns no output.  If the second player tries to send a move, he
gets a message saying that it's not his turn, and shows the board.  Like so:

---------------------------
Instructor@Instructor /cygdrive/c/temp
$ ./tictactoe move 9 test1 test1 1

Instructor@Instructor /cygdrive/c/temp
$ ./tictactoe move 9 test2 test2 1
From: Richard's PBeM Server <pbmserv@gamerz.net>
Message-Id: <pbmserv.1120082477.3784.9@play.gamerz.net>
To: test1@abacustech.info
Subject: TicTacToe Board 9 Error

It is not your move

Summary of TicTacToe Board 9

Please start the game test1.

   Ohs (o)      Eks (x)
   test1        test2
