I'm hoping to do this 2-3 times a year, if I can get enough interest and nail down the material. Mind you, the price will be going up past this "beta" run.
If you follow me on twitter (@daeken) or subscribe to the RSS feed on my blog, you'll get updates as they come out. If this all goes well, there will likely be another run starting in Q1 2014.
I, and may be some other folks, can not do this now, but would love to some time later.
