Looks like it's actually submitted them unbeknown to me, unfortunately i re-submitted the same tutorial half a dozen times because of the error (trying various browsers, clearing cache etc) so now theres a page full. Oops. Can't see a way to delete them myself. Sorry about that. @Kyatric @Arima please delete.

Thanks for report, can't pinpoint exact cause but am looking into it. If you submit, it will publish. Am uploading a bit of code to help pinpoint it.

For the record, I have never actually ran a website so don't take my comments personally. I'm venting more than anything and my comments in no way reflect my opinion of the admins here.
