Participate

If you’re handy with PHP, jQuery and Code Igniter we encourage you to become a committer! Help us move Compost forward and give back to the open source community.
To get started, visit the project at Google Code – there you can familiarize yourself with the issues, checkout the source code and browse changes. You will need to be a member of the project to commit any changes – to become a member, send an email to gavin.blair at rtraction.com and I’ll add you as a committer.
If you’re not a coder you can still help out by testing Compost and providing feedback.
Coming Soon
Very soon Compost will have an iPhone app, drag-and-drop design ordering, and email notification options. What features would you like to see in Compost? Leave a comment below or at our feedback site.

Hey! Looks good. Just about to download and install it.
However, I am curious as to what features will be available on the iPhone?

The iPhone version is still in the planning stages. My goal is to be able to manage every aspect of your Compost on the iPhone as well as in a full browser. Additional features that make use of the phone’s camera and microphone may be introduced as well.
You can keep an eye on the iPhone version at http://code.google.com/p/compost-rtraction/issues/detail?id=20
