In the above, we see a chain of length 3, where treehouse now has 2 admins (barb and alice) and 1 "writer" (carter). Carter can write files and chats, but he cannot edit the signature chain, since he's not an admin. How they would've done this, command-line edition Alice: keybase team create treehouse
keybase team add-member treehouse --user=barb --role=admin Then later, Barb: keybase team add-member treehouse --user=carter --role=writer It's that easy.
