Where can I ask a question about arrangement of numbered lists of axioms in a mathematical manuscript?
- tex.stackexchange.com? (i think no, because it is not specific to TeX)
Academia is not for domain-specific questions about academic subjects. It's for questions about academia itself.
And just because a Stack Exchange looks like it ought to be the closest fit for a question, does not mean that a question belongs there. Most questions don't belong on any Stack Exchange site.
