We've opened up the GitHub repository that we've been using to collaborate on the the Facebook plugin. It's at https://github.com/facebook/wordpress/.
If there's a feature of bug that you've been aching to see in the plugin, you can now help us out by contributing code directly. The feedback and response to the plugin has been phenomenal and we look forward to see that carry over to GitHub.
If you plan on contributing code, please create an issue on GitHub so that we can discuss it. Once your code is ready, submit a pull request from your branch and reference the issue (https://help.github.com/articles/fork-a-repo).
If you're not contributing code, please continue using this forum to note bugs and feature requests. We'll triage them and create relevant issues in GitHub.
Note that all contributors must agree to and sign the Facebook CLA prior to submitting Pull Requests. We can't accept Pull Requests until this document is signed and submitted.
We're looking forward to coding with all of you. Thanks!
