Starting with version 6.3, CourseForum and ProjectForum can display mathematics, entered into the forum using TeX formatting commands.
This is accomplished using jsMath, an open source Javascript library that replaces TeX formatted math expressions in a web page with HTML including images representing various symbols.
To use this feature, you first need to install the support files for jsMath, which are not included with CourseForum and ProjectForum (with the included math fonts, they're approximately 80mb).
Download the file jsMath.zip. Then unzip it into your "Course Data" or "Group Data" directory, so that you end up with the "jsMath" directory immediately inside the "Course Data" or "Group Data" directory.
Note: This is based on jsMath-3.6a, and jsMath-fonts-1.3. If you want to use a newer version of jsMath, you'll probably want to adjust the settings in jsMath/easy/load.js.
After the jsMath files are installed, you can use math in your pages using the new "math:" link prefix. So for example:
[math:a=n \times \sum sin(\theta)]
In the formatted page, this will display like:
