First I inserted a internal link inside the content, but removed it in a edit after nothing was posted on given time. I thought that maybe the markdown syntax for links could be misinterpreted.
Next I thought I mixed up the time zones and compared my current time to ET and EST and refreshed my browser after the planned submission.
But still, the creation does not work. Why is this? Am I unable to see the wood for the trees? A typo maybe?
Thanks for your help!
