Is it legal to publish an Open Access article at MDPI and then reupload this article after publication at researchgate? Furthermore, is it possible to change the layout of the article into a standard 2-column article for the upload at researchgate? I am asking because I do not know if there are any legal issues with this.
I am not very happy with the layout of articles at mdpi, but I didnt came across a different publisher, that is that fast, which is the reason I choose mdpi.
