I started working on an 'official' Subsim wiki. I know there was an existing Wiki community archiving SH3 wisdom, but I thought it'd be nice to have a place where all that knowledge came together, and where you could find information about every subsim out there, not just the latest ones.
So, if you think this is a good idea, feel free to sign up and help out!
