I almost never use the word Tribe either, but because the question invited me to think about what it meant to me, that's what went in the entry. Like you, I have used "chosen family". I don't use it often.
There's definitely another category in between "community" and what I've here called "tribe". There are lots of shadings of the word "friend". One of those shadings involves some level of trust and willingness / desire to help, and you'd definitely be in there, despite the fact we've barely met in person. A different shading of "friend" involves someone I don't know well but do see frequently and feel generally well disposed towards. :-) Obviously, the way I use the word "friend" is pretty vague!
