I couldn't find on the front page how to make a custom poster... I had to click on a premade one to see that I could edit it (and I only did after checking the comments here).

Plus I had to read the very long introduction text to know what this what about. My advice: let me play with the interesting stuff right away, or at least tell me clearly in one sentence what I can do on this site. It will most certainly improve your conversion rate.

Great stuff, but a little too hard to figure out !
