Hi!
I use power-CMS on a site for teaching mathematics.
I have to be able to use in dynamic content ranges Latex code that is interpreted on the fly by MathJax plugin. For this, I must be able to enter without being eliminated by the publisher backslash (\). example
$\ sum_ {k = 0} ^ {n} {\ frac {1} {k (k +1)}$.
How to set the editor such as this becomes possible?
Sorry for my broken English.
Regards

Olivier Walter
