Hi Manuel, great job on this new feature. It's very engaging - reward based learning is always effective for me, and it works well as a form of interactive user guide for the PHP Classes site, so I think there's a lot of benefit to be gained by contributors for completing the missions (on top of the badges!).
I'm looking forward to seeing what's coming in future iterations. Good luck!

Yes, the badges are just symbols of the work each author have put in making their contributions available in a manner that makes their work more visible.
The important is that authors do their share of work on a voluntary basis, but in the end they are the ones that benefit the most of engaging in these missions eventually learning details they were not aware explained in the mission briefings.
