Are you also grateful to elementary OS developers? If so, you can give something back by helping the development team confirming bug reports. Here are the details as said by Daniel Foré at Google Plus:
Community, I need your help.
We have 1,500 “new” bug reports (or 1 report for every 10 of you). That means they’re reports that we haven’t had time to verify. We could really use some help confirming these reports. Doing this is easy peasy:
Pick a bug report.
Try to reproduce it based on the description.
If you can reproduce, mark it “confirmed”.
If you can’t reproduce it, mark it “incomplete” and comment asking the OP if they can still reproduce the bug.
That’s it 🙂
