This is my favorite 40k community, and I suspect you will find plenty of quality, reasonable people here, in both the Mods and the users.
I mostly lurk and read, but every time I've posted something, I've had positive, engaged responses.
Every instance I've seen in which a Mod has had to step in, it has been clearly explained what has gone wrong, and how it can be avoided in the future (often: here are the community guidelines. Read them and follow them).
In short; welcome to Advanced Tau Tacticia!
