Before you click "Save", I think there is a drop down menu on the top right. It stays at "Draft" by default. Isn't there a "Submitted" option? I think you have to change it from Draft, and then Robin (or any other possible admin) needs to review it before it gets posted.
So either you need to change that option, or they just haven't been able to review your post yet. I know a lot of people in Holland go on holiday in the month of July.
Hope that helps.
