When you create a paper for Royal Society Open Science using the RMarkdown template in rticles, it will include a box at the bottom that reads:
© 2014 The Authors. Published by the Royal Society under the terms of the Creative Commons Attribution License About The Licenses - Creative Commons by/4.0/, which permits unrestricted use, provided the original author and source are credited.
We are going to post our submission as a preprint, so it will be confusing for readers -- they may think the paper has already been submitted. I don't see how to remove this or turn the paper into a draft (rsos_draft is not recognized)
