As to why there is no "issues" flair, one reason for that is that there is a separate community !piefed_help@piefed.social for that. I believe that you are welcome to use either one but the thinking may have been that there it is an "issue" whereas here it is a "question".
@rimu@piefed.social it may help to mention that other community explicitly in the sidebar, just so people are more aware that they have multiple options to choose from?
