0: The post appears to be missing a link.

1: In order to submit a link using Hacker News |submit| page, the text box for writing comments must be blank, otherwise its contents will be used instead of the link. The |submit| page only allows a link or text, not both. It defaults to text if both are present.

2: If it meets the guidelines, this might make a good 'Show HN'. Show HN guidelines: https://news.ycombinator.com/showhn.html

3: After submitting {only} a link to a project, it is ok to then add a comment after the submission shows up on the |new| page.

Good luck.
