Guys & gals, I just discovered that after a game is done, you can add some post-mortem notes to the Notebook. At least, it worked for me in a game my opp. resigned. True, you're limited to the size of the notebook, but if you want to list some continuations after a resignation, this may do the trick for you.
Just open the game from your games list as usual, key into the Notebook and save the notebook changes.
