I use User ultra membership on my site. Do you know if they would work together? http://usersultra.com/
Your plugin looks amazing but it is real important that everything works together. And I can't see if the pro has what I want which is:
Example on a post: at top of post displays this: "Overall rating: ★★★★★ based on 1 reviews" (yellow stars google rich text friendly)
Then at bottom of post displays (prefer tabbed layout)
1st tab "Community Reviews"
Displays all reviews
Second tab "Submit a review" Review Title Rating (5 yellow star seo friendly layout) Review (comment like box)
