Pttn, Thanks for taking the lead on this. I'm happy to be a developer.

Cryptapus, I'll take a look at the gitian code.

There is not much needed to finish the 0.16.3 code. I need to review the gitian changes. We need to set the blocks that BIP65 and BIP66 will become active. We need to decide if we would like the ability to activate segwit or csv. CLTV and CSV should probably be tested. There are a couple things that I added to the code for testing like getwork support that can be removed now.

More developers would be great. Aside from testing CSV and CLTV there probably isn't much to do until after 0.16.3 is released. You could start looking at changes needed in 0.17 code. There will be plenty to do in upgrading the algorithm which is really my biggest interest. We also need web developers.
