Hello, first of all I'd like to thank the developer for this great and simple free plug-in.
Here are some suggests :
1) User could submit a question and get notified when it's answered
Like available in the plugin FAQs manager (http://wordpress.org/extend/plugins/faqs-manager/) it would be great if the user could ask a question and have it submitted in a queue of pending questions. The webmaster would then at the same time answer the question, modify the title if needed, and have it published.
2) User could rate a question/answer
Like available in the plugin Q and A (http://wordpress.org/extend/plugins/q-and-a/) it would be great if the people reading the blog could rate the answer (hit a star if the answer was helpful, or rate out of 5 stars, etc...) so the webmaster would know which answers are most popular
3) "Expand all" / "Close all"
Like available in the plugin Q and A : the possibility for the user to expand all / close all the questions and answers.
Thanks a lot for reading these suggestions, I hope the plugin author will be able to work on this !
