Marek,

They are both based on the original Codebook 3.0 created by Flash. I believe the main difference is in the documentation. I started with the original Codebook 3.0 and struggled mightily. It wasn't until I found the Mere Mortals guide that I made any progress towards using the framework. Flash has done some very interesting things in their version 6.0, but it is still difficult to start with unless you have a solid backround in OOP and n-tier development. If you do not have this experience, I highly recommend looking at Mere Mortals (30 day free trial). I think you will be impressed with the quality of both the code and documentation. At the same time you can also look at 6.0 from Flash.

Kind Regards,

Mat
