I've remade Koeln (I refuse to call it by current name) in its entirety, some Nomicrons, deleted entire Discovery repository by accident, poked Durandal/Alley for months until someone adjusted Thebes for me, stood up and defended Molly's Guard assets (que: current Poole). Even wrote some rumors for Omicron Delta and other places.
I am pretty sure I left my mark here without compromising my own ideals.
