Jreviews

Hello
I want to buy Easy Social which i found it very usefull and i thing its a great one joomla extensions. I want to ask you a few things and i will be very happy if you answer me back!

I am making a web site using the jreviews but uforunatelly i couldn't find a demo with the two components together to see how it works, thats why i have some questions.

I want to make 4 group of users and as i checked at the demo of easy social its easy to create.

Can you tell me if it is possible every user group to have different access to the listings? I mean the first group only to make reviews an not to submit new listing. And the others group to rate different creteria in the same category.
For example if i had a category called used cars i want one group pf users to rate for the price and the condition kai the other group to rate for something else. Is it possible to be done?

My second question:
When you create a user group you gine a title (lets say register users as you have at the demo) can this title be show at the profil page? and is it possible someone to see all the users of a specific user group by clicking this title?

And my last question:
As i saw you have a badge system. Is it possible these badges to be visible at the profil next to the number of the points or is it possible to be visible below the avatar image next to the title of the reveiw you make as it is at tripadvisor?

Thanks in adbance
