 * /referral, /beta and /bounty are views of the same points and link here.
 *
 * Signed out it opens on the public board (names only for people who listed
 * them), with what earns and every badge locked. Signed in it opens on the
 * reader's Overview: level, lifetime points, the next level and achievements,
 * what to try next, their posts and their rank to share. Nothing on it is a
 * figure the cloud did not answer.
