* LaTeX addon:
I have created an 'LaTeX' addon to let posters add equations to their their miniBB posts. The addon uses the mimetex cgi binary ( http://www.forkosh.com/mimetex.html
). You enter equations inside [tex][/tex] BBcodes using the LaTeX typesetting language (see the mimetex link for examples and further info).
* Code addon:
I took the solution I developed for the LaTeX addon to avoid any smiley and bbcode replacement inside the [tex] bbcodes, and also made it to work as a separate 'plain proportional text' addon. Hence, the Code addon basically does the same as the "official" 'preformatted text solution', but with the addition of not subsituting bbcodes and smileys inside the [code][/code] environment. Very convinient, especially if you happen to discuss markup code...
The addons are available for download from here: http://www.dewmill.com/minibb.html
Hope you find them useful,
