It should probably be fine to upload the FAQ, anyway.
For the rules, I'd try getting in touch with the designer.
I've tried to get in touch with Dave Chapel but the only contact I have is his geekmail here and I suspect it's rarely (or never) checked.
The FAQ/errata document is actually already archived online here. It was quite useful in sorting out a few ambiguities from the rulebook but there are others for which I'd be interested to know designer intent....although I suspect it's ancient history now (no pun intended) and players would need to work out solutions for themselves.
