How do I preview LaTeX code before posting?

[topsquark]

Just a quick question... I haven't been able to figure out a way to preview my posts before I post them. Is there a way to check my LaTeX code on site before I actually post?

Thanks!

You probably have to reload the page if MathJax is not loaded (ie, nobody has yet used it on that page).

The MathJax resource is not loaded if the page does not have any $\LaTeX$. When you are creating a new thread, as @Orodruin has said above, you need to refresh the page once to load the resource, and thereafter the preview will render the $\LaTeX$. Before refreshing the page, however, make sure you copy everything you have written. There is a bug that renders some of the $\LaTeX$ in the edit window itself after you refresh the page, and then if you click the Preview button, everything will be garbled.

When I want to write longer things, I use mathb.in
Then I do a search and replace all "$" with "##"
