I'd start here - https://www.netbsd.org/docs/guide/en/chap-cgd.html and point your IRC client to #netbsd on irc.freenode.net.
Thanks! I've tried out most of the other common BSDs (FreeBSD, OpenBSD, DragonflyBSD, and TrueOS) but I've always had more trouble with NetBSD for some reason. Hopefully I'll have better luck with it this time!
And good luck with your NetBSD journey, with or without FDE. I've thoroughly enjoyed my years with it as my primary OS.
