An off-topic question requesting Where to get feedback on homebrews was just asked. I left this comment below:
Welcome to rpg.se! Take the [tour] and visit the [help center] to learn how things work around here. This question will likely get closed as a shopping question, which are off-topic here. We have a [list of forums on meta]. You might also be interested in [How can I ask a good homebrew review question] for getting reviews here on the stack.
As I was writing it, it felt more like an answer. However I don't think we should be answering off-topic questions. What is the correct approach here?
I also posted it as a community wiki answer. I wondering if this is the best way to handle it. I didn't want to earn rep from answering an off-topic question.
