There is now a backup copy of this forum at our home page (not linked on any of the web pages yet.) If this forum goes down, and you need to refer to an old post, you can find it here -
It's read-only. And some of the links will lead you back here, to the real forum, if it's up.
Edit: I deleted it after I realized all the advertising links are active. The link above will lead you to a compressed archive: forum_archive.tar.xz (or possibly something similar, with a date.)
Download it, unpack it somewhere in your home directory, and open index.html.
Archive file is 9.6MB, and it unpacks to around 220MB.
No guarantees on how often I'll update it, but the forum gets backed up a couple times a week. If we go out for more than a couple hours, there's a good chance I'll update the tarball.
