We have three templates for new questions (for apps, libraries and scripts):

They'll insert a body like this:

<!-- thumbnail: https://example.com/some-image.png -->
<!-- version: 1.0 -->
<!-- tag: a-tag-on-the-post -->
<!-- excerpt: Up to 200 characters of excerpt -->

##Screenshot / Code Snippet

Insert a reasonably sized screenshot (or code snippet) of your 
app here, so we can get a quick look at it and 
an idea of how it works and what it might do for us.

...

which unfortunately isn't compatible with CommonMark. So new questions like this one end up poorly formatted. Can the templates please be updated?
