P.S.S. If you do decide to use the Interactive Diagram, you will need to lean HTML in order to properly embed one in your pages.
That isn't really necessary. The editors in the article-submission page can be switched to WYSIWYG mode. You can type your text there, and then swicth them back to 'Source Code' to get the corresponding HTML. Only in the section that will contain the Diagram you cannot do that. But the Setup section doesn't have to contain anything other than a Diagram. So you can always leave the edit window for that in HTML mode, and just paste the HTML code for an Interactive Diagram there that you obtained from the Play-Test Applet.
The PTA can also supply you with a nice table (with piece images) for pasting in the Pieces section in Source-Code mode. That you can switch safely to WYSIWIG, for editing the descriptions.
