answers_best_answer.module in Answers 7.4

Support selection of 'Best Answers' for the 'Answers' module.

This file allows question authors and site managers to select a best answer for a question.

Only a single best answer can be selected.

To configure the module, go to admin/config/content/answers. The site administrator can choose:

• Whether questions will automatically be locked after a best answer is selected
• Whether best answers are locked (and cannot be changed) after a question is locked

Users with the 'manage answers content' permission can always set and modify best answers regardless of question locks.
