Anybody who wants to help fix the FAQ, that would be grand. I started
going through it earlier but there are so many entries, and so many of
them have become subtly (or obviously) wrong in the past years, and also
many of them are not FA anymore.
The second best way to contribute is to generate a diff -u on
https://www.torproject.org/docs/en/faq.wml
and open a ticket about it on trac.torproject.org in component website.
(The best way to contribute is to git clone the webwml repo, and make a
git branch with your change, and then open the ticket and point to your
git branch. But that's a lot more work than just making a diff -u.)
