1) You have support for mongodb but to get started I need the authorization package to. Your auth pakage dosent support mongoDB and thats a big setback for me. So my suggestion is that you add support for mongoDB in your auth package.
2) To get the auth package to work you will need to add support for session class to. So my next suggestion is that you add support for mongoDB in the session class.
I have been following you for a year no and i have seen that the community have grown. Specialy in Japan. I have been tinking about building a CMS on your framework, but I think its a bit early yet. Maby I will get started when framework is on version 2.0. I will give you a tell if i do. Keep up the good work.
There's a new Query Builder in the making, which will also introduce proper MongoDB support. We're waiting for that to be completed to add more MongoDB to the core.
