Being very new at this, I'm about to ask a 'newbie' question. Is it
possible to add multiple comment lines in a signature? I've received a
number of emails which have included up to 3 separate comment lines
containing such things as website url, email address to send to for
receiving the sender's Public Key, etc. If this is possible in Enigmail,
would someone be kind enough to explain how?

Very many thanks,
