After much delay an initial version of Brezina's homepage went online at last. The site is currently German only, but there are among many other languages also English prints of his book available.
Xoops has been hacked to allow for a different theme per "section". That means each of Brezina's series is displayed in another style. Existing modules have been hacked to assign their topics/categories/... to Brezina's book series.
I really would like see this feature been built into Xoops. I'm talking of a "section" framework for modules, btw.
