Most memorable time for me was when we had an XA promotion ceremony, when myself and Tubalcaine (you need to get your game working, Tube...) were promoted to Royal. We had no clue what was going on until it happened, with nearly every XA at the time online and at Ouray. After that, we celebrated by completely destroying the Colorado system.... the gate from NY might as well have gone straight to Kepler once we were done that day.
Other than that, some of the more outrageous piratical acts the Buccaneers have done are quite memorable.
