At the time where I didn't have a math.stackexchange account, I could ask questions as a guest. At mathoverflow, I can still ask questions as a guest. But if I click on "Ask question" at math.stackexchange, it says that I should log in. Thus my question is:
Is there somehow a way to be able to ask questions as a guest on math.stackexchange again? I tried deleting the cookies from my computer, but the problem was still there.
