It's always nice to learn something new. I decidet to start tiny ERP system with Fuel PHP as RPC backend and evntualy extjs 4 as a frontend. The project is located on github: malko-erp.
I'm a long time CodeIgniter user. Just recently I found Fuel and it looks like it has the best from both Kohana and CodeIgniter. I'm looking forward to learn Fuel, and the best way to learn a framework is to actually use it in a project.
Do you have an idea of a project?
