Didn't know where to put this since it's neither a bug or feature request, so I'm putting it here. If there's a better spot, let me know.

The limit for source URLs on image posts was raised awhile ago from 5 to 10, but it appears the text in the post edit box wasn't updated. So folk who didn't read the site news don't know about the limit change and will still think it's 5. Hopefully someone who can change it will read this.
