1. Please upgrade Recaptcha to support the latest version. Some sort of captcha is vital nowadays, but it's behind the times using an old version of Google's Recaptcha when a much better version is available.

2. It makes sense to restrict the number of reviews each user can make. However, this restriction is annoying when entering from the frontend or when testing functions as the admin. Allow, in Permissions, a checkbox for overrides.

3. Add the module to the component download and install. It took me ages to find where it was and download off your site. At least add it automatically to the Download Area. Almost every other component has this functionality. At the same time, include the captcha plugin.
