It looks like all the reviews (up to 02-FEB-04 or 11-FEB-04) are intact at the Internet Archive. Off the top of my head (w/o doing any further research) I'm pretty sure it would be reasonably easy to harvest the reviews. There's software out there that can do that kind of thing or a perl/ruby script can be written or something. Getting the comments on the reviews might be more problematic (or not).

Or maybe email the administrators and see if they'll tar/zip an archive of the review pages and email them.

Maybe this has been considered and already rejected, but if not its worth considering. What to do with them after they've been gotten is another issue for another day.

Oops. Didn't see Johannes' post.
