Hi Carsten,

The option "#+OPTIONS ^:nil" did the trick with underlines and hats, but Greek
letter are still replaced. Since they are ignored by jsMath I get the correct
equations and the only minor annoyance is that the font of the Greek letters is
not as nice as if it were replace by jsMath (jsMath fonts are equivalent to
latex fonts). If it is something easy to do, an option to also turn-off the
replacements of Greek letters by org-mode would be nice, but don't bother if it
is to much work.

I'll write the instructions of how to use jsMath with org-mode here soon.
Thanks Carsten,

Darlan
