I need a component for joomla that can do the same as yahoo answers. The difference is that we will have only 1 category and subcategories will be created by an admin (or even include more categories).
I should say that anwers only can be answered by the persons (admins or editors in joomla) that have the right to get into this component and answer.
Questions will published without admin authorization but can delete questions from the administrator if they are not appropiate.
