Unfortunately, we've had quite a rash of empty or otherwise-pointless categorized answers submitted by Anonymous Monk.

So, from now on, you must be logged in if you want to add a categorized answer to Categorized Questions and Answers.

I would prefer to allow anonymous contributions to Cat Q+A, but the lack of feedback channels to Anonymous Monk has proved to be a problem.

BTW, please familiarize yourself with the purpose of Cat Q+A before adding either answers or questions there. It is not meant for discussions nor for subtle side issues. It is meant to hold simple, frequently-asked questions and simple, best-practice answers. It is fine to include pointers to more in-depth discussions, especially as part of a simple, best-practices answer, but in this section "clear" is more important than "complete".
