What are the best practices for marking a forum thread as "resolved" or "completed"?

To mark a forum thread as "resolved" or "completed," it is best practice to clearly state in the thread title that the issue has been resolved. Additionally, you can add a final comment summarizing the solution and thanking those who helped. Finally, consider marking the thread as "resolved" or "completed" using the forum's built-in tools if available.
