Just stumbled upon this, was thinking of writing my own framework, but CodeIgniter seems to be just what I was looking for, and now I have found PyroCMS which is the whole idea behind writing a framework in the first place, so I would be willing to help on this if I can.
Got a few questions for you though ...
I dont actually see any license details on the PyroCMS webpage can you shed any light on this?
Also, what are the chances of seeing the database schema?
And this forum post is getting a bit long, so do you have plans of hosting a forum on the Pyro website?
