Changes

* <code>create [public] [relay] beacon [beacon name] [@username @username...]</code> will create a beacon by that name. Names can only be alphanumeric, underscore, a few other little characters. Spaces will be removed. If you make it "public", it will be listed when anyone asks to show beacons. If you make it a relay beacon, anyone subscribed can publish to it. If you include usernames at the end, it will allow all of those users to publish to the beacon in addition to you.* <code>edit [public] [relay] beacon [beacon name] [@username @username...]</code> changes the publishers and whether the beacon is public or private.

* <code>show beacons</code> will list all public beacons, or all public beacons and your beacons, if you ask in a PM. Beacons with a <code>(r)</code> are "relay" beacons.
