For those who have been reading my signature for the past year or so...
My XinTwo website now has nearly 100 micro lessons up - with about 100 more in various states of construction.
I did a small, quiet intro at NAB last year, but soon after, I heard about the possibility of the big FCP X changes that became the 10.3 update - and I didn't want to keep producing content with the old FCP X interface. So I semi-parked the initiative until I could study the changes and incorporate them into the XinTwo lessons.
There's a free week trial at http://www.xintwo.com - or just hang on - I"m getting the links set up to embed a few sample lessons right here on the Cow.
