This is a special category of topics that make it easier to get help from the community as well as to offer your help to others in need. “Question / problem topics” are marked with an orange dot and a label showing if that problem is already solved or not, so community members can easily spot topics where others are looking for help as well as quickly browse through already known and resolved issues.
Inside such a topic, the original poster outlines a problem while others try to solve it by giving helpful information or hints. What differentiates these topics from normal discussions is not only a strict rule to stay on topic and try to solve the problem but also the topic creator's ability to mark a specific post as the solution. If your post gets chosen as the solution to the outlined question / problem, it will be marked with a green “solution” label and you will get a nice rep boost. You can easily track your posted questions and received answers using the “My questions” section.
