For those that missed the event as they couldn't get in the same instance the key thing is communication. Either via teamspeak or Discord, get invited to a wing with someone who is already there, and once there drop from the wing to allow more people in. That's how it was done and it worked well until we reached 100, and then the drops started.
If you are not in teamspeak or Discord I recommend it, not only for the event, but for the banter that went on yesterday with Dr. Kaii, it was superb, best moment in ED so far.
I may have been the exception to this....
I jumped into SagA* a good hour before the planned meetup, saw a few contacts but nothing much going on. I checked with Teamspeak and the channels were basically empty (no one really speaking). With no real idea what was going on I spotted a low wake and randomly clicked on it.
Followed it in and found myself looking at this group of about 16 ships all being herded by an Asp acting like an Orchestral conductor. With no idea of what was happening I wandered closer and pinged off a message asking where everyone was talking. "Discord" came the answer.
So in the middle of the slowly growing fleet I popped back to Windows, installed and registered discord, got myself into the chat and was asked to move my ship next to the Wasp. Still none the wiser I did so and only then asked "Errrr.... I don't want to sound stupid, but what exactly is going on?"
Yeah... everyone laughed
I genuinely had NO idea it was the planned meet up! Just absolute pure luck and an insatiable curiosity got me into the biggest gathering in the game
I'd still love to know what FD did to get it working because it seems pretty obvious we broke the game afterwards.
There was one odd thing though: after every disconnect I would always join back in the main instance, I don't know how many others this happened to but I never once had to jump back in or wing up. Straight back to the meeting point every time.
