OpenPSA is under constant development and you're welcome to join in! Please see below on how to get started:
The bug tracker can be found here.
To submit patches, just fork the repository on github and send pull requests when you're done. For development-related questions, please refer to the developer mailing list.
Right now, OpenPSA's UI is fully translated into German and English, we also have quite good coverage of Finnish and some other languages, but would of course love to broaden our reach, so if you're interested in translating the UI into your language, just get in touch!
