I just read this topic, where the problem is solved in reply #4, but the user then goes on raising a new problem. Should we then ask the user to post that as a new question or just continue on the same topic?
Supporting within-topic is user-friendly for that one user but not for others. Supporting on a new topic is cumbersome for that one user, but helpful for others. I would tend to go for the latter since I think that we’re helping many others than just the one who asked the question. And that the list of topics serves as a kind of documentation. What do you think, @jon, @m-macaskill, @jeremygray?
