In order to get user support on TeXmacs, the best thing you can do (especially when you are a novice) is to suscribe to the TeXmacs mailing list <texmacs-users@texmacs.org>, by sending an email to <sympa@texmacs.org> with a subject of the form
SUBSCRIBE texmacs-users Your Full Name
You may unsubscribe later on by sending an email to <sympa@texmacs.org> with
SIGNOFF texmacs-users
as subject. The texmacs-users mailing list archives are also available without subscription.
