If you have a space for questions and answers you can make it easier for readers to see which is the best answer to a question.
Select the Actions button under the appropriate response and select the Choose as accepted answer option. Now when people view the thread, the accepted answer message will be shown at the top of the thread. In searches accepted answers will also appear higher in the results than other messages.
When viewing discussion threads or messages on index pages, a tick icon will be shown alongside the subject to let you know that the thread contains an accepted answer or a message is an answer.
If you decide you don't want a message to be the accepted answer after all then select the Actions button under the message and select the Remove as accepted answer option. You can also switch the answer to a different message if needed.
