The V-Files : (Canadian)
The X- Files (Australian Conne-X-ion) : The X-Files Australian Conne-X-ion contains all the latest X-Files news relevant to Australia, an episode guide with my personal ratings of each show, a multimedia section showing what's available in Australia, a links page, poll and an expanding section showing how The X-Files is reported in the Australian media. Yes, I'm lazy. I copied that blurb. ;)

Die Wahrheit ist hier drinnen : Alas, even German sites can be prone to false advertising. The Truth is not in this site!! However, it it nonetheless a cool German page - fanfic, the Speech from the end of the FTF Soundtrack, and other things.
