Hello Alan, wanted to reach out and offer any advice I can. I've not been an ND very long, but I can share some of the mistakes and successes that I've had.
You need to take stock of your guys; your relationship to them, and their current level of commitment to the org. First thing: communication. Make sure you and everyone in your NW check rocket consistently and respond to messages. Good comm is key.
Start putting some basic requirements for activism and fitness in place, but don't start out demanding too much. If some guys are used to chilling and not being very active, asking too much of them from the get-go can make them feel overworked, or even resentful (in my case two former NWs merged, I asked for too much at the start from guys who barely knew me).
Take some time to meet everyone in your NW, and get to know them. It takes some time to get to know everyone, but those bonds will be strong. You probably have 1-2 guys in mind that you are close to and trust absolutely. I made a NW2 Leadership chat for these two men, the Scribe and Quartermaster. Very helpful in considering decisions and relaying info. My QM was the local leader from the other NW we merged with, and that has been a huge asset.
