String Replacement for latex


New member
in my old vb forum I was using [tex] [/tex] tag to parse latext expression with a cgi.
Now I would like to replace them with double dollar $$. How can I do it automatically?

If I edit a post I have to reload the page to recall the mathjax function. There is a way to disable ajax and directly reload the page when a user edit or preview his post?

Thank you!
