add a way to find/connect with my friends on Riffle (rather than browsing the suggestions offered).
This feature has been added! Go to read.rifflebooks.com, click on the ‘People’ Tab at the top. See that you can find Suggested Users, Facebook Friends (or Twitter Friends), or Find people by typing in their name. Best, Marquina and Riffle Support
I agree. I have many friends that have joined, yet I have no way of locating them. I've stumbled upon a few, but I would like to find the rest.
