Head over to http://mimir.planewalker.com for a view of the site from just before we went down. I'm updating this snap shot with material as I locate it, so some of the links are iffy. This snapshot is the copy I'll be using for importing material back into the current version of the site as we go. All files (pdfs, rtfs, etc) are perfectly safe - so this should let you get at the links in the meantime.
We'll update the site with a more direct download asap! :)
