What is the best way to go about asking another user a question that is relevant to Emacs, but perhaps tangential to any given question?
For example, what if a user posts screenshots and I want to know what theme they are using? Or what font they are using? Or what package they are using to get their mode-line to look like that? Or what they are using to record gifs?
I often find myself wanting to ask other users about these things. However, I have seen long conversations like this one, and understand that there isn't really a way to send a private message to another user - I also understand, and agree with the reasoning behind this. However, I also don't know how the community feels about off-topic comments on questions. Maybe the question is "How do I do X in Emacs?". It is probably not the most productive/helpful thing to start a conversion in the comments along the lines of:
What theme are you using in those screenshots?
How do I get it?
You can get it from MELPA
I see multiple themes with zenburn in their names, which one specifically are you using?
Of course, this is a particularly annoying example, and it would probably stop at the second comment in most cases. So, would this kind of exchange in the comments be frowned upon/discouraged by the community, or is it OK? Would it be better to take a screenshot of their screenshot and ask another question? Ask in comments and then delete comments later to remove noise? Other possibilities? I have been wondering about this recently, and I was curious if there is an established/suggested way to ask these kinds of questions.
