Yesterday, I wrote a short text novel, and I tried to publish it on DA. First surprise, there is sort of a rule that makes a "preview image" mandatory. I did not expect it, but if this is the rule (not really user-friendly) I followed all the steps to upload first my text, then I edited one of my pictures to become the missing "preview image", and used the "change preview image" button. To no avail. It just does not work. I re-tried it many times, the thing is mandatory and it does not work. If there is a moderator or an advanced user here able to give me an answer? Ok, I will wait some time. Until my patience wears out. Then I will begin to destroy my DA page, and look for another site for my art.
