Ich serve on the editorial board of Friesische Blätter, which promotes truth and reason.
When I was a student of mathematics at the University of Frankfurt, I have been writing for the lokal students magazine Fachschaftszeitung "wenn...dann" (if...then). It is remarkable that this journal exists by now for twenty years which is a long time for a students magazine.
I have written some LaTeX packages, which might be usefull for other people, as well.
