Idea with testnet for NN seems very good, it allows candidates confirm their skills and learn something new about NN work, dPOW and other things. But idea with bounty for NN, if i'm understood it correctly (VOTE2018 bounty for notarizations counts in testnet, right?) - seems not so good. For example, my server declared in proposal is ready, but it will be transferred to DC in first days of April. So, now to take part pursuit for the bounty i'll need to deploy test NN in VM insfrastructure at home.

2SHossainKMD: Thx for your guides for NN testnet, i hope it will help candidates to learn the basics. Good work!
