I assume it has reached a consensus that a finished archiving of a site, is the site in a localized state, completely functional on any host, or on an individual machine, with all necessary files intact, and all links made relative as best they can be. The format of a post will be broken into two sections, In Progress, what you are currently working on, and Completed, what has been finished in terms of preservation and localization. For example:
Original Site URL (where it can be found on IGN until August 31st) - New Site URL (where it is now being hosted if available) - Archive URL (standalone zip of the site for anyone to grab)
I stress the importance of not just hosting these sites elsewhere, but also making available the standalone form of them to others, that way many of us can keep hold of Quake's history, and thus be less vulnerable to the normal ravages of the internet. This is an act of investing in our own community, and an act of historical preservation.
If you would like to contribute, the standard method seems to be using wget (on Linux or Windows) or HTTrack. I myself use wget for Windows, and have met with rather good success thus far. I hope you have the same, or better success, and together we can preserve the best community the internet has seen.
