Good Mornign tgarfield.

Thank you for your message. We are always looking for ways on improving our website for the benefit of all our members. A non linear formula would require quite the algorithm in order to prove succesful and it will take time to troubleshoot any bugs that might appear.

We have added your request to our AGORACOM members wishlist and will be looking into improving our rating sytem in future upgrades.

Thanks again for your message and your contributions within the AGORACOM community.

Regards,

AGORACOM
