I think I get what you mean. A simple hyperlink could be generated between identically named categories.
For example, CGI Programming would contain a link Categorised Q&A, and the page QandASection: CGI programming would contain a link Code Catacombs, displayed fairly promenantly.
Tutorials would need integrating in a similar fashion, because the section doesn't currently have a node for each category.
Oh Lord, won’t you burn me a Knoppix CD ?
My friends all rate Windows, I must disagree.
Your powers of persuasion will set them all free,
So oh Lord, won’t you burn me a Knoppix CD ?
