I've archived the entirety of Story Games discussions and comments on my GitHub account, here:https://github.com/jeffschecter/storygames
I've got a script that lets me quickly update the archive with recent threads and comments. The crawl script is in the repo, so you can create your own version of the archive if you like.
At the moment it's just raw HTML, with some of the boilerplate removed. I might do some postprocessing later to clean it up and make it more legible, either as raw text files, or as HTML with some of the formatting added back in.
If someone wanted to, they could potentially use this as base to take over the storygames domain name, and provide a static archive website that would correctly resolve external links to discussions and threads.
