[texhax] faq in texhax footer

[Karl Berry]

rf> to avoid further embarrassment, i'll see if i can dissuade karl berry
rf> from advertising my faq in the footer lines of texhax posts.

FYI ... I discussed this with Robin and persuaded him that it was ok for
it to stay.  The FAQ is one of the most useful places to point users,
especially new users.  I want to "advertise" it.

(Robin asked me to post this resolution.  He chose not to stay on the
list himself.)

Best,
Karl
