Sub-forums under a master?

So basically you’re saying to use the idea of “Categories” to segregate a forum into subforums (where category is a synonym for topic and a forum would have different topics of discussion).

So the /c/ stands for category for major segregation purposes. (Might be a smart feature to allow for a configuration override vs having to make permalinks. Interesting. I’ll have to play with this a bit and see how this fits.)

Is there per chance a way to customize appearance on a per “category” basis in order to give different CSS options for each one? For example, if - from my example - the main idea of the forum is “education” (very broad) and then it has sections such as math, it might be useful to then have math centric logos and various things going on there…

I guess this could be more comparable to StackExchange with a main big holder with different sub stacks like StackOverflow, etc… It would be nice if Discourse facilitated this style of segregation and specialization for large community building…
