@100daysindieweb Hooray for helping out the less Indie-capable!

From a UI perspective, some might not quite know what you mean by IndieNews URL, to put in the proper one. I suspect it's there to differentiate between the various languages, in which case perhaps a dropdown with the different language versions instead of a more ominous empty box might be better? Gen2+ are more likely to be confused.

Additionally, how many do you suppose will find/hit the endpoint this way? Perhaps updating news.Indieweb.org to have the submission box on the submissions page like the one you added on day 9 (https://aaronparecki.com/2016/12/29/9/day-9) to your own site would be even more helpful? Or perhaps even easier, adding the URL for the endpoint to https://news.indieweb.org/how-to-submit-a-post in the documentation and listing it as alternative option. (Or were you keeping this for a lighter Day 41 on a busy Monday?)

I can't believe it's been 40 days already!!! Kudos again.
