I don't think api v2 supports custom fields. Hell, it doesn't even support all oob fields (I may be thinking constraints...) 😛
If it does, though, I'd love to know as well.
Side note, wouldn't it be in the users collection?
SELECT profile.receive_community_news FROM users WHERE id = '65'
In the past, Khoros added user metadata fields for me and I used API v1 like this:
/users/id/${user.id}/profiles/name/metadata_field
I couldn't find it the first either, so I asked support how to and they helped me with the url.
