Comment on More Controversy Over Open-Access Publisher MDPI by Jeffrey Beall

I don’t see any major problems with this publisher. It appears that they are open access but don’t charge article processing fees at this time. I did see a couple small examples of plagiarism and self-plagiarism. The publisher requires copyright transfer. The papers bear a copyright statement but are open access. I will not be adding this publisher to my list at this time. It looks like they are putting in much effort to operate professionally.
