I don't think we've discussed the organization of the math forums in quite some time. It does sound like they are organized around common courses in math curricula, but since we have expanded the HW forums (last year) and all the HW questions should go there, not in the main math forums, this organization may be outdated.
Keep in mind that there are sometimes also practical considerations, such as the popularity of a topic, for whether it gets its own forum or gets lumped together with other topics.
These are the full titles of the subforums in math:
General Math
Calculus & Analysis
Differential Equations
Linear & Abstract Algebra
Tensor Analysis & Differential Geometry
Set Theory, Logic, Probability, Statistics
Number Theory
DeadWolfe, how many combinatorics threads are there currently to warrant giving it its own section?
Keep in mind that we also from time to time collapse forums together as well. If there just aren't enough posts under a topic to warrant keeping it as its own subforum, it'll get combined with something else.
So, with those criteria, that there needs to be enough sustained interest in a topic to maintain it as an active subforum, and topics that are somewhat related can be combined in order to create an active subforum where each individual one would not be active enough, AND, most importantly, that we try to keep the number of forums and subforums here a low as reasonably possible to avoid being too overwhelmingly cluttered or so narrow in focus for each subforum that discussion is hindered, would you still recommend changing the topics?
If so, please, offer your suggestions of what you would include as subforums and provide some support for that organization (i.e., relatedness of topics, activity of threads on those topics, etc.)
Also, remember that "General" in our topic headings is NOT the same as it is for courses...it doesn't mean "introductory level" but more "miscellaneous," so anything that isn't active enough to fit under a more specific subforum can and should be posted under the "general" forums.
