I know this has been answered a million times, but I am using math type and I want to know how to post it on forums. I know how to change mathtype into LaTex, but I don't know how to get the LaTex to show up in html.

On this forum specifically, or on any site in general?

 

For SFN, just stick the LaTeX code into [math][/math] tags. There's also a tutorial here.

 

For other sites, you'll want to make it into an image to stick into your HTML. I'm not sure what the best way of doing that is.
