We are going to publish a revamped izpack.org website soon. To do that, we will use GitHub Pages and Jekyll.
The current version is live at http://izpack.github.com/ and is updated whenever a commit is made to the master branch.
We would appreciate to get your feedback before we switch izpack.org to this new version.
We would also gladly consider any contribution that you would like to make to the website. It's as easy as sending a pull request to https://github.com/izpack/izpack.github.com :-)
