Hi!

I've used to a long time my CI based blog. So, I thought, make a connector Windows Live Writer reaching my blog to write and modify posts. But I can't how it works. As my opinion, a common API needs in my CI blog.
Wordpress, Blogger, etc. can handle it, but the source code is hard for me to implement for CI.
Has anybody idea for my problem (or a semi-completed code :lol?
