No thanks. I would not be able to have unemployment benefits while doing volunteer work in my country.

Technically you can, but they have to approve and it cannot compete with the "normal" job market (which it would, as open source is generally competing with proprietary software, and it's normally my job to write software)

why 3rd party petition site instead the official one provided by the gov?

It's pretty cool you guys are credited in some way for volunteering. Good luck with this :)

It wasn't? Why?
