What would be good is if there was a popup questionnaire, that showed up after 2 or 3 days of using a certain theme or skin, where there would be an option to complete a short form that asked you questions on the theme's/skin's performance and then it generated the rating number for you, and automatically sent it to the site.
This would make the rating system more constant, and more credible.
What do you think I’m sure this could be done some how?
