I believe it was Gurth who, after getting a mail from me with a bunch of Shadowrun-related questions, kindly told me about ShadowRN and Dumpshock.
I didn't have much Internet access back then, so I just joined ShadowRN and took a brief look at DS. Some time later (a year or so), I dug out that mail from my mail accound and decided to take a look again.
Shortly after that, I joined and ranted about the lack of information about South America. Someone (Synner) told me that if I wanted something, I might as well propose for it.
The rest, as they say, is history.
