Café de Nuit

On the fraternity websites, under DM Resources, there are several web erratas and enhancements for 3e books pubblished by sword and sorcery.
Are they official by any means or are they made by random people?
Normally i would've been inclined to say that they aren't since the FAQs seems to imply so but at the end of the PDFs the text feels ambiguous.
For reference:

This document is a web enhancement of Van Richten’s Arsenal Volume I, a D20 Ravenloft book released by Sword & Sorcery Studios.
DUNGEONS & DRAGONS, D&D, and RAVENLOFT, are trademarks of Wizards of the Coast, Inc., a subsidiary of Hasbro, Inc., and are

Kind regards,

This WE was released by Sword and Sorcery, who was publishing Ravenloft in the 3e era. It was written by the authors of VRA.

So yes, you can consider all those files under this section of the site as officials.

Now, for this section: you have an "errata" marking (self explanatory, it's official) and the other errors spotted by fans where no official errata was ever proposed.
