Classifieds Q&A Directory all default WP Registration?

I just signed up with you guys. I have to say that I am disappointed to see that your plugins like Q&A (classifieds and directory too?) force visitors to the WP backend to register, etc... I really don't understand this. I have several sites using various themes and plugins , some with user generated content/listings, and have not come across this before. It is all front-end for the visitors. Your plugins seem archaic, very old-fashioned.
I think I may have misunderstood your products . It seems they are geared towards developer/users rather than typical non-tech type site visitors. I apologize if I sound harsh, but please take it as constructive criticism rather than complaining. There are lots of great front-end plugins out there that make the UI much more enjoyable.
Thanks for listening.
