First, I appreciate your effort in developing this plugin even though it is not free. There are a lot of issues with this plugin. I have used free q&a on wordpress.org before and they are very user friendly and easy to use, to insert on the any page, to list questions and insert question form shortcode. You don`t have to make this plugin complex by overlooking to build shortcodes to make this plugin worth the money we pay for it. I think I have to go and settle for one of those free q&a plugin.
