February 6's newsletter had my question at the very end of its list (under the section "Can you answer these questions?"): It says, "answered by Oscar Lanzi". However, if you have a look at the actual question, it was answered by "Soumik Das" instead. What is going on here? Is this a bug?

My teacher told me about resonance and explained it as different structures which are flipping back and forth and that we only observe a sort of average structure. How does this work? Why do the different structures not exist on their own?
