I've come up with some kind of idea: Microtasks. And what is a Microtask? It's easy
There are many people who are afraid of joining an Open Source project because they think it means some constant dedication to the project. While this is sometimes true, it is also true that there are also some other smaller tasks that need to be done within the same project, from time to time, meaning no commitment, constant collaboration or anything. Those tasks normally take only a few hours and are usually very simple, and once they're done, we don't have to think about them anymore.
Somebody has to do those little tasks. If the development team has to take care of them, it means that we won't have so much time to code other much cooler features but we are of course not forcing anybody to do this. We just think it would help but it is now up to you
I'll post the first one asap
