Suggest a good site

Your own or somebody else's

Did you see a good site that you think deserves certification, or would you like to register the site of your community for the site certification process? Leaving the information on the form does not obligate you in any way. We will not share your email address with others or spam you. The basic idea of Green Thumb is that we represent the needs of the users and thus serve the designers and publishers of websites. Therefore, we encourage everyone to submit quality sites to the process. The Green Thumb certificate on the site tells the visitor that the site has been found safe and functions well.

The Green Thumb certification process comprises 120 different features to consider and is completely independent. If a site is awarded a certificate, we will contact its owner and offer the opportunity to use the Green Thumb certificate on the site and in communications. The fee for using the certificate is 800 € + VAT/year.
