First of all, I have to say, that the component works fine itself.
Then, it has an excellent support. My new hosting provider forbade standard cronjob command 'wget'. So the notifications about new questions ceased to work. But support team successfully and fast (!) resolved this problem by adding of new codes to component files in order to be compatible with the 'curl' command.
I think, that this fact speaks a lot of good about the product and its creators.
