I remember all of those websites. I worked on JKMAG for a bit after Chyren left. I didn't do much other than moderate the forums, which I eventually had to close due to piracy issues, and run a one time JK IRC tournament that went over quite well. The tournament was host to 50-60 JKers, many of which were top players, and that's no small feat for a group of people that were that entrenched to the Zone.
Hyperview was a great site. Kurgan, you remember that one side...JK Depot or something similar? That was a great site as well. Many files from both of those sites will never be experienced by anyone again.
