BuddyPress.org

I can’t make assumptions about the parent/child relationship between categories. Specifically what use that relationship will be put to. Perhaps in some environment the parent category will not be displayed for selection and only the children will.

The relationship still exists even selecting just the child.

Actually I had intended to eliminate the profile tag display altogether. I just forgot to do it. I don’t want to force the display of something in a theme. It was a design decision to omit the category profile display and an omission to omit the tag display. Huh?

I’d prefer to leave the inclusion of those things up to theme authors and site admins.
