We are looking for experienced providers to code & deliver a Question/Answer application where users post questions for the community to answer.

Our application is a Q&A app, with some difference. The application is about users posting “topical” questions – for example questions about what to buy or questions about a job. Selection of a topic determines the fields that the questioner needs to fill out (see below). The community then answers the questions or provides feedback through comments.  

Basic Flow
Users post questions to the community using one of the question templates from the system. A question template gives the user a form with all the required and optional fields that are appropriate to the topic of the question. Before the question is posted, the questioner can choose to either receive private or public answers. Private answers are only visible to the answerer & the questioner whereas public answers are visible to all.

A registered user can respond to a question in one of two ways. First, a question can simply be commented on. Comments are used by the users to either clarify a question or to make a suggestion etc. Second, a question can be answered to which can then be either accepted or responded to by the questioner. It is important to understand the difference between comments & answers. Comments are short text-only messages. Answers, on the other hand, can be longer and can have other fields besides the response text.

Once a questioner receives an answer, he can either accept it or reply to it with a comment for further clarification. Accepting an answer closes the question to further answers and comments. Comments that are posted against an answer follow the visibility rules of the answer. If the answer is private then the comments are only visible to the questioner and the answerer.

A user can also follow users and, in fact, individual questions. Followed users and questions generate activity that is show in the user’s feed. The feed also contains information about the user’s own questions and answers.
