- Find alternative hosting, especially if it's ad-free!
I think someone already mentioned Google Pages: ad-free, and the only thing you need to sign up is a gmail account, for which I'd be happy to provide an invite if you don't already have one. You'd get 100MB of space instead of 20MB, giving you plenty of room to grow, and a WYSIWYG editor to help as you're learning the HTML. And really, it would only take a matter of seconds to transfer the files you've already created on Angelfire over, so there's not much incentive to stay with a service that's going to slap ads all across your page.
When it comes to domain names, if you'd rather not spend anything on one just yet, you can always get a free .tk URL (
http://www.dot.tk/). People would be far more likely to come back if they can remember the address.
Oh, and Peter had a good point about running a competition to write a newer, better version of TPP: whether you think it's out of date as a piece or not, having people compete--and starting with something that many people are already aware of--would get them involved with the site, and you would have the beginnings of the community that will be essential to the site's growth if you intend for it to be anything more than a mission statement and a list of members.
Finally, I'm sure opposition groups rose in the past for Lord of the Rings and other such adaptations. Take a look at their sites, how they were structured, how they covered news, how frequently they updated, and how they got people to come back--or how they screwed things up, as the case may be.
Best of luck--even if I am curious to see how the movie turns out
