I made a links section. For the past week I have gone through dozens, literally nearly a hundred links looking for more. I think I might have exhausted everything that can be trivially found without connections.
So towards the end I started going a little crazy looking for any more leads. On Songhigh Knoll I found evidence of a "message maker" and even found a picture of it in the Furcadia archives. It looks like one part Animal Crossing mail, one part that sticker drawing game every edutainment game has. I wanted any information on this and the frustration got so bad that I actually got the 1997 Furcadia archive.org client connecting to a local server.
... and that's as far as it went. I couldn't figure out how to get the client to let me initiate the mysterious Message Maker. I'm not even convinced that it's accessible through the version I have, though text strings related to it still exist in the EXE.
Finally, to get some closure, I downloaded the new Furcadia and played with its map editor for 5 seconds. I did not play the game itself. The new map editor is fine I guess.
I dumped all the stickers that the Message Maker comes with into bmp files, but there's like 400 of them and it's going to be a pain. And I guess I still need to tackle the maps available on the official Patch Archive, but I have no idea if that will make me feel better or worse.
