There was a lot of drama in the past regarding people who helped nas out. Nas is trying to protect his most dedicated players by not allowing them to be in a situation where they're targeted the same way that one good guy was.
It also doesn't help that there are literal bounties out to get his code. And then there's the threats... and issues with multiple people being accountable for things etc, etc
If you want to contribute to the server, do things that will save his time otherwise, so that he can better spend it doing dev stuff, like helping new players with install or gameplay issues in naschat. He also often says "just invite your friends, and play fair" when asked if someone can help him. So, just be a good player and be friendly.
There isn't much left for nas to do to get the server in a flawless state, either. The amount of bugs and their nature these days is much smaller and simpler than in the past.
Personally, I'd really like it if someone helped contribute to the naswiki. Chakan is doing a great job with it and I appreciate it. But damn it'd be nice if someone ported over quest and monster info to our wiki so that people wouldn't be confused about the differences between retail and here. The troubleshooting page (
