You can mark a thread as "Resolved" only if you started the thread and the thread is in a forum that uses the "Resolved" thread prefix.
To mark a thread resolved:
- Click the Edit button under the first post in the thread.
- Change the Prefix drop-down in front of the thread title to Resolved.
- Click the Save button.
Marking a thread as Resolved is a hint to others that a solution or explanation was found or that you no longer need help or advice. It does not close the thread or prevent others from making comments if the subject is still of interest to them.
