Okay lads so the Engage conference is happening in an hour. As far as I can tell there isn't actually a limit to who can join and the signups literally didn't matter as it will all be under public instances for most with there being special VIP instances for press and partners. Unfortunately my 4chan press credentials weren't accepted, I tried.

Posting instructions I received for anyone interested in sitting in on this.
