First of all great work with this plugin!
I have a few questions in order to use this at a website I'm still working on:
1 - I know that we can customize with css but I'm a noob at it, so is it possible to hide the plugin rating box and make the visual for the user using built in shortcodes (which is "compatible" with my theme's style)? But I want to do it in a way that Google can see that I provided this to the user.
2 - I have a working rel=author on my site, but will it work together with the review microdata e show at the search results the rating and link to my google plus profile?
3 - The plugin uses a 1 to 5 rating, but I'd like to use from 1 to 10 with the possibility of adding something like 7.8 rating. Is it possible? Because the rating would be an average of others.
This site is something pretty close of what I want to accomplish: http://info.abril.com.br/reviews/tvs/samsung-un40f5500.shtml
