We need this option. There needs to be a button next to the Quick Reply and Multi-Quote... maybe a Star icon that lets the OP say "This is the answer to my question" and closes the thread automatically. It also flags the thread as ANSWER and maybe gives it a light green highlight or something to help other users with the same problem.. An example of why I'm requesting this is, THIS THREAD. It keeps appearing in the newest posts, and I go into it expecting something new, but it's either the same answer as post 2, some flaming, or off-topic convo. Just an idea.
