Pretty easy setup, and that’s with me running it on a first gen optiplex (ancient hardware). I use it more as a cloud drive than a collaboration tool. I opted out of all the collaborative/social features (office, talk, activity status, etc)

It’s been mostly set and forget for me.

Frankly the community here isn’t big enough to start breaking up into niche sub-interests.

I’d say just post here whatever you would there, and eventually you can create that community once traffic increases.
