Get it Here

I found this little fic here:

http://web.archive.org/web/20041221114516/www.mags-nificent.com/MSW/Lost/Dart.htm

and read the completed work from the wayback machine.

In it, there is a note that Thyme had written an alternate ending:
http://web.archive.org/web/20061030220306/www.mags-nificent.com/MSW/Lost/Dart2.htm

On the alternate ending page is a note that "Sandi" had only posted 5 chapters at ATP.
Thyme picked it up from there not knowing that Sandi had finished the fic - at least her 12 chapters.

I went to ATP and could find no reference to "the dartmouth series" or Sandi.

There is a note that Sandi had given the MST permission to continue the series - thus Thyme's story, but I can't find it posted by her anywhere.

I finally found Thyme's redo here:
http://www.mags-nificent.com/MSW/TF/Dartmouth.htm

With an explanation regarding that Sandi wanted to have her stories taken down.
A little poking around shows that Sandi's fic was pre April 2003.

The way back machine doesn't appear to have content for MST prior.

Does anyone know anywhere her other stories may be archived or found?
Is she writing under another name?

ETA: It appears that Sandi's writing is gone with the wind. Try reading Thyme's take on this plot.
