As soon as I purchased this CoAssemble deal AppSumo was all over me asking me to leave a review ... which I am hesitant to do because I haven't had time to use the product yet - I just barely bought it. I will say that the buying and registering process went smoothly and that my stacked purchase was activated by the CoAssemble team within an hour or two even though I purchased on the weekend (Saturday). Also, I reached out to "support" with a question which was answered by email within a very reasonable amount of time. Beyond that, I have nothing to review because I haven't had time yet to get into the platform and create a course. Sorry AppSumo, I'm just being honest here, but I can't leave any kind of product review until I've actually used the product. Steve
