You should find them there in a few hours (by, say, 6PM EST, 27-Feb-2012), if you prefer buying them there. But, if you buy them directly from here, you’ll get updates up to a week or two faster. (I get a larger share of the proceeds, too.)
The first version is numbered 1.02, for sale now at just $1.99. Downloads work as a trial for up to 10 lessons.
All betas have now been rendered nonoperational.
New beta version (1.01B2) now works on Tiger. (The previous version was supposed to, but didn’t because of a missing font.)
Just added to the web site; read about it there.
Beta is free. For MacOS 10.4 (Tiger) through 10.7 (Lion).
