It took me a while to wrangle the massive blob of changes we've been making to SMF into logically separate git commits, but I've pushed our source to GitHub:
https://github.com/theflatearthsociety/forum.tfes.orgThe GitHub source is
slightly different from what the forum is currently running on, as I've made small fixes where appropriate. We'll be migrating to a new and better-managed deployment system based on the code in git Real Soon Now.
