PMAS is a Puella Magi Madoka Magica quest. If you haven't seen Madoka Magica, I'll try not to spoil it, but suffice to say that the quest revolves around a massively overpowered OC player character trying to fix a crapsack world (quite a bit like Uplift, actually). Due to the PC's overpoweredness, the main challenges of the quest are social in nature. The main posters spend about as much effort figuring out exactly what to say to people as the MfD hivemind spends on WMDs. It's to the point that ideas about how to use the PC's powers better in combat are frequently rebuffed by the main posters, on account of the PC being OP enough already and the belief that the thread's time would be better spent on social stuff.
Interestingly, while in MfD most salt is almost exclusively between the players and the QMs (it seems to rarely be player vs player), in PMAS salt flows freely between players but never touches the QM (the players frequently have flamewars between each other, but almost never say anything bad about the QM).
PMAS goes slowly. VERY slowly. As in, after several years, they are still in the second week of the quest in character.
