Hi webmaster,
Thanks for the suggestions. The required shortcodes are actually on the front page (description) of the plugin:
[submit-review]: displays a form that allows visitors to submit a review of a product that you or they specify
[ultimate-reviews]: displays all reviews or all reviews of a specified product
Sorry for the lack of documentation, we’ve only been developing the plugin for a short bit of time, and it’s still in a beta stage. What version are you using that doesn’t save the overall score? There was a bug earlier that would only save the scores on the front-end, not through the admin area, but it should be fixed at this point. Please let us know if that’s not the case, as we’d love to track down any remaining bugs.
