CMS for CI?

[eluser]CodeIgniterNewbie[/eluser]
I'm about to redevelop a web app (dating-site type website). Right now, I am about to wrap up splitting of all my view files (I'm using Smarty), creating controllers for each page (my architectural rule is: 1 page, 1 controller), etc. By next week, I expect to have a completely "static" site that is integrated in CI.

The current app has the "core" dating-site features (e.g. users can create accounts, search for other accounts, etc.). I'd like to be able to do more than just that (e.g. post articles, etc.) -- things that a CMS would normally handle and something I don't want to develop myself.

Are there any CI-based CMS that I can use that will integrate easily in my current app? In the existing app, I used Wordpress to handle the "CMS" stuff and CI to handle the dating-site stuff. It works, but it's a bit kludgy.

Suggestions?

PS - I don't want to pay for EE.
