Reading it right now, that was a lot of work

well done
I added this as a comment:
Upon proposal/submitting of a new Sphere there should be a sum of MVT to be deposited (how much need to be decided), this will serve as:
- spam filter
- a guarantee that the project is legitimate
- to "rent" land in Greenpoint.
Once the Sphere get approved by the vote of the token holders, the MVT deposited are moved in a general Fund/Wallet of the Movement which can be used to fund internal projects/works/contest or anything generally useful.
If the Sphere does not get approved the MVT are returned.
I reworked that section of the proposal below your comment. Let me know what your thoughts and then I'll update the proposal. I may also have to redo that section of the flowchart as well.
thanks!
