Other things to do
Search for new exciting tasks.
Find new tasks either in Bugzilla or resolve more newcomer tasks until you feel comfortable with the workflow. Every bug is a new learning experience and eventually you can search for other tasks yourself that are not newcomer, you will find issues and ideas you want to implement yourself the more you use the app.
Triage bug reports that are filed in Bugzilla.
You can go to the bugs reported to the app and try to reproduce and say whether you need more information from the reporter, whether you can reproduce and provide some more details, or implement it yourself.
Interact with other contributors.
We strive to be a friendly and open community. You are encouraged hang around in IRC and participate in discussions as you wish. It's in the chat rooms that you have the chance to get to know fellow contributors and teams.
