I just happened to see this, so I hope what I have to say helps out a bit, I Hate to see good stories lost because of glitches or some other matter.
A little intro, I hold a hobby domain and a UBB license, I work as a network analyst for a major corporation and do a bit of science fiction/fantasy writing as a hobby. I know the pain of storywriters, boards administrators, network traffic issues, and domain holders.
Here's what I do, when I have a story thread going and I want to make sure that the work that everyone puts into it stays relatively "safe" somewhere, you might give this a try, I hope it works for you:
Depending on your PC operating system and your browser (I'm assuming you have a Windows OS and either IE or Netscape) you can pull up say, page 1 in your browser, and click "File", then "Save as", then save the page on your hard drive. You can do this with each page, and it saves images off the page into a folder, and also a copy of the html into an html file.
If you wish, depending on your situation, you can perhaps find some "friendly" free site on the internet and upload your html pages to it so that people can see them if need be. Or, you can simply keep them on your hard drive, and depending on your knowledge of html you can edit out some of the icons, buttons, and such, and simply save the text.
You can save each boards page in this way (you do need to do each page seperately and name each page uniquely) once it fills up an entire boards page or intermittently if you wish.
I don't recommend this often, and it Is best for all concerned that you do your page backups during some other time than prime time (U.S.A. daytime) to reduce strain on the boards server.
Sorry this is long, I merely hope it helps you out in some manner.
