Hello,
Just wanted to share a website I developed:
www.umerefer.com. u.me refer connects users looking to exchange referrals. From the homepage, you can use filters to immediately connect with a user who wants your referral and who has a referral that you want. This, of course, will work better and better as the community grows. Examples of referrals on the site include referrals for credit card rewards (airline, hotel, cashback), Airbnb, Plastiq, Uber, Google Express, and so on.
I've made two big assumptions in building this site. (1) You will have more success getting referral rewards if you make a good faith effort to use other's referrals. Users who request referrals when they offer referrals are already one step ahead in terms of making a good faith effort, in my opinion. They can confirm their commitment to using another's referral via private message, and then follow up with data points (e.g., approved or not) after the agreement. Users can follow other trusted users. I hope to add ratings at some point. And you are free to use the name from your forum of choice so people recognize you.
(2) My site connects users more effectively than websites/forums. I'm not aware of another site where you can click two boxes and immediately find someone who wants your referral and who has a referral that you want.
Please let me know what you think. And feel free to make a listing to get started earning more rewards.
Edit: twitter handle is @umerefer, in case you think the site is useful and want to spread the word through there.
