Hi, 

Can you please try to fill in the ranking of project proposals
in the sheet prepared by Nir here:

https://docs.google.com/spreadsheets/d/1Nf7yHO7-S-BJlr9ntqkZUQVIas4_WZC954RRT8yqAH0/edit?usp=sharing

the selection must be fnalized by 1PM UTC today, we we have 7 viable proposals
and 5 slots (+ probably one more in SoCiS).
