This event was a good idea, and if everything went well, it would have been extremely fun. The concept was good.
There are a few things that could be done to improve this event.
First, raise the player cap. The server used to accommodate 255 players years ago, and 160 was considered a light amount of players. Why, now, years later, with technology being cheaper and more available, does the server support a cap of 110? I understand that less people play, but why limit it so that when people actually want to log in, they can't? Why not leave the cap high, so if the server was ever to increase in activity, it would have room to do so? Have you cheaped out and downgraded your server, despite still receiving donations to improve it? It should be able to handle more than it used to; not less. During this event, there was not enough room for people to log on and we actually did hit the 110 cap.
Second, have a roster for the event. If it seems like more than 12 people will be present, then split the event into multiple systems so that there will be less lag. You could have had 1 cruiser in New london, 1 cruiser in Cambridge, and 1 cruiser in Manchester, splitting the players up so that there would be less lag.
In case you wonder: "What is this lag you speak of?" Players' torpedoes were not moving. They were sitting in space. The frame rate was reduced, and ships were just teleporting around.
All-in-all, good job preparing the last event, but there were a couple of problems that you didn't anticipate, that I think you should have by now.
