How can you help the project?
First of all, you can do some coding. Take a look at Jira and pick an outstanding issue.
Second, if you can help with documentation, just ask for an account that allows you to edit the wiki.
Third, we can use a lot of help with the hosting. We're not experts in much of the stack that we're using to host this web site, so if you know a lot about the Atlassian tools, or Postgres, please offer to help.
