I have almost all of Season 5 and Season 6 as well as the Unfinished Fifth Season in my personal archive.
If someone wants copies to upload to an archive, I have them available.
I actually have all of the stories in two formats:
TXT format as downloaded
and
Word with added formatting and graphics.
Edit: In going over my files I find that I am missing Episode 19 of Season 5. If anyone has it they can e-mail it to me, my e-mail address is in all of my story posts.. Also I have episodes 1 - 14 of season 6. If it went beyond that, I can't help you.
I have started compiling and formatting the files into single documents and will be producing epub and mobi files of the three seasons for anyone interested.
