How do you mark a post as "Resolved" or add an "Update" for closure?

Reddit does not have a native universal "Resolved" button that applies across all communities the way some dedicated Q&A platforms do. Different communities handle post closure and resolution in different ways, and understanding the convention for your specific community is important. Some communities — particularly advice subreddits like r/legaladvice or r/relationship_advice — have a bot-mediated system where the original poster can type a command like "!solved" or "!answered" in a comment to mark the post as resolved. The bot then adds a flair or label to the post indicating that a satisfactory answer was found, which helps moderators and other users scan the feed and prioritize unanswered questions. Check whether the community you are posting in has such a system by reading its rules or sidebar. In communities without a formal resolution system, the conventional approach is to add an edit to the original post body with a clearly labeled "Update:" or "EDIT:" section at the bottom. This update should summarize the outcome and, if advice was sought, describe what action you took and what resulted. Providing closure is considered good etiquette, particularly in support and advice communities where members invest time responding to your situation and are often genuinely curious about what happened. For posts that generated significant discussion and where a meaningful development has occurred, posting a follow-up as a new post is also appropriate. Many communities actively welcome update posts and have a dedicated flair for them. An update post allows for fresh discussion around the new development rather than burying it in an edit of the original. When posting an update as a new thread, including a link to the original post in the body helps new readers understand the full context and honors the investment of people who engaged with the original. When writing a closure update, being honest about the outcome — even if it was not the outcome you hoped for or that commenters advised — adds to the community's collective value. People who invest time responding to questions do so partly because they are genuinely curious about what happens. A resolution that notes "I followed the advice here and it did not work out the way I hoped, but here is what I learned" is more useful to future readers than a vague positive closure.
