@llorllale Just for curiosity, what are your criteria to put an issue in scope?

[llorllale]

@fabriciofx you made me stop to think :)

See, the point was to focus on releasing 1.0. Pretty soon, all you guys will have > 1024 points or whatever and will be kicked out of this sandbox project. :(

But I have been including tasks not necessary for 1.0, which means I haven't been consistent. I will rectify this.

@llorllale I've asked it because I've opened many issues and corrected the bug in jcabi-parent and I haven't get any points for them. I made this contribution because I like these projects and love contribute with open source, but if I can do it and receive some points at Zerocracy too, it's even better, right? 😄

Besides you made me think about it too: I think interesting have a possibility to someone with more than 1024 points and was kicked of a sandbox project, returned if he/she want to. WDYT?

@fabriciofx I'd first like to know how to unset sandbox status.
