There was a discussion on cstheory meta about adding Math.SE to the list of target sites in the off-topic flagging wizard. When a non-research-level theory question is closed as off-topic, we usually suggest Math.SE as the alternative SE site where OP may repost the question1, so adding Math.SE to the wizard's list seems a reasonable idea to us, but we wanted to check that you are OK with it before making a request to SE admins. :)
. We assumed that (similar to MathOverflow) Math.SE users think of TCS as a subfield of math and therefore theory questions are in the scope of Math.SE. I think most of non-research-level questions we get on cstheory are undergraduate level questions in logic, combinatorics, design and analysis of data-structures and algorithms, complexity theory, formal languages, and computability.
