A new website was found by Sin_Vraal:

http://www.hcrd.org/. This is the home of the Historical Criminal Research Department, which was referenced in September, then in one of Zeladzny's files at research.nru.us.

There's a research website up at NRU: research.nru.us.

Catalina First National Bank: www.catalinafirst.com

This is a great reference site for Acheron: http://acheron.netninja.com/. It includes conversation logs, puzzles, flowcharts, and a navigation bar. Very cool!

Found in the source code of the Cypher-Systems contact page: http://www.rootsweb.com/~wiwaupac/FamilyandFolk/FF133.jpg. The picture has a subtitle of "Is This The John Baxter Family?" - John Baxter is another one of Reggie's aliases. There is another image in the same archive, located at http://www.rootsweb.com/~wiwaupac/FamilyandFolk/FF134.jpg with the subtitle, "Is This John & Elvira Baxter's Son?". Could it possibly be a picture of Reggie? Could this mean that Reggie has done some time travel?

On 12/3, www.acheron.us changed to a "This domain has been purchased" page with a logo for a company called Cypher-Systems. Someone found a web page located at www.cypher-systems.com with the same logo. Therefore it looks like the Acheron main page is now in-game, and the Cypher-Systems page is also.
