Can I have a more user friendly referral code?
Yes, you certainly can! Later versions of MageRewards actually allow you to enter the configuration section of MageRewards and select an option to enable shortened referral keys. Go to Rewards>Configuration, click on Referral Program and select "Yes" for "Display short affiliate code". This will make it so that your affiliates can spread the word about your site and brands in a much more use friendly way!
