Thanks! And it'll get better until release early March :)

Indeed, good luck! Especially since we cannot give any practical advice
regarding how people can know whether their hardware is trustworthy or not.

So I added something that could point to /doc/about/warning more in general:

« Still, Tails cannot always protect you if you install it from a
computer with viruses or if you use it on a computer with malicious
hardware, like keyloggers. »

I changed it to:

« All the memory is deleted when shutting down. »

Quite more than 6000 actually:

# grep '^r ' /var/lib/tor/cached-microdesc-consensus | wc -l

I already spotted this since Saturday and changed it to "open". Also,
diversity doesn't really fit in this section while "open" gives emphasis
to "nonprofit".
