Podpora Markdown syntaxe
na začátek odesílané zprávy stačí přidat:
#!markdown
a zpráva se pak prožene Markdown procesorem (spouštěno přes sudo pod jiným uživatelem)
a pak teprve přes standardní XSL transformaci.

1) Vytvořit uživatele a skupinu markdown

2) Do /etc/sudoers přidat:
Cmnd_Alias MARKDOWN = /usr/bin/markdown
%markdown ALL = (%markdown) NOPASSWD : MARKDOWN

3) Uivatele, pod kterým běží NNTP démon, přidat do skupiny markdown
