Thanks for the prompt reply. Looks pretty much like the Wikipedia/MediaWiki syntax. That's good, IMHO. Less to learn, and a move towards some sort of standardization.
While wikitalk initially seems less than intuitive to "newbies" it's a lot easier than html, and my hope is that as students use more and more wikis, they will already know how to "write" them when they get to a new one.
I hesitate to say it, but NWiki looks close to a MediaWiki in Moodle.
Is this accidental or on purpose?
Not a criticism by any way...but desirable.
