A quick update on the diagram situation. Now what I am using is Aquarium 2012. I use the "ibook HTML for blog" option after clicking the "Web Export" button in the ribbon on the "Publish" tab.
The one weird thing I ran into was that at first there were some problems with the board. These problems were mysteriously cured when the number of the replay boards gets over 5 on the whole blog. I can't explain why that is, but it's been repeatable for me that this solves the problems.
That should explain why I post the two games of mine and the Greco games. Anyway, Greco's cool!
