Congratulations Thafool, I look forward to more insane level missions now that you have a Heavy Cruiser.
Yes the lounge is a good place to meet, but this isn't going to be a fixed time event. So just use the Fleet tab to see which members are in game and we will try to create teams in the rough level range to do missions.
At some point in the day, if was have a bunch of toons in the right level range, I would like to get multiple 5 Captain teams to do a fleet action. That would be epic.
