A while ago I've done some new hooks to Kunena and created a plugin to add LaTeX parsing to Kunena as BBCode tag. I needed this for the website of my student council and thought why I should not share the plugin.
It is the first extension which is not free, not even in a basic version. Why? Was a long thinking of me, but to keep the extension up to date and do a good service I have to charge a little bit of money for it. You can subscribe at the subscription area. Kunena and Joomla! are fast growing with a lot of extensions and templates which where changing a lot.
You think it's to much? Write into the forum!
Documentation and demo will follow.
