I'm not sure if Steve (Bink) still has this one listed, but I have another one that got left out...
I worked with Rob Michnick, Russ Siegelman and others on the first iteration of MSN...whoops, that should read msn

We had two complete server farms for MSN 1.0 - Marvel (which was the actua production & customer / user-facing system) and Manga (which was the isolated Test system to thoroughly test whatever content and architecture changes we needed to make before the content went "live"). We also affectionately called the MSN Networking Hub "MosWEST" (Microsoft Online Services WEST), in honor of the MaeWEST NAP (Network Access Point) in Santa Clara, CA.
Just some more tidbits...
