Developing Content Management System With CodeIgniter

Hi!
I wrote new blog post about developing CMS with CI. This post and the future posts on this subject wouldn't contain too much of a code, but only explain the design I chose for my CMS and why.
You can develop an application in so many different ways, I believe my way is good - I will be happy to see your comments about it.
