This plugin is used to access the Unasked.com api and allows the following usage:
Allow your user to ask questions
Allow your users to answer questions
When a user asks a question, the question will be automatically inserted into UnAsked.com which allows our community to answer questions originating from your site. The question page on UnAsked will also show a link back to the original question page (on your site). For example, you will notice a link right below the question on the following URL: http://unasked.com/question/view/id/120476. This indicates that this question originated on HowToGetRidofStuff?.com
When a question is answered, an email will be sent to the asker with a link to YOUR page. This means that visitors will come back to your site to see answers regardless of where the question was answered (whether it was answered on UnAsked.com or the originating question site). The questions on your site will no longer go unanswered.
