Subject: Favourites
Recommending, or creating, a single post is enough for the board to reach your Favourites.

Why?

Why not give members direct control over what boards they want to be their favorites?

There very well be boards I want to follow but have not yet felt the urge to post on.

And opposite of that, back on old TMF, I may have posted once or twice on PA, in response to a Best Of, but that is far far away from me having any desire for making that board a favorite.
