This isn't exactly about time-travel, but... I'm trying to build a web-page about interstellar travel... (It could be time travel, if you accelerate next to the speed of light), and I was wondering if anybody would like to co-author some of the sections. They could send in material through e-mail, and I would post it on the page. Here's the address people get when they try to access it now: http://www.geocities.com/ProgBoy1/StarWisp/, and they get an 'Under Construction' page. But you can see the nearly completed page under http://www.geocities.com/ProgBoy1/StarWisp/main.html. None of the links are completed yet, except for a forum... So e-mail me if you'd like to do it!
