[Plugin: UMatter2Us] I've downloaded it and it has nothing in it!!!

Sorry about that. I am one of the developers for the UM2Us plugin as a senior project at James Madison University. Our goal is to have it up and running in the next couple months. I appreciate the interest you have shown in the plugin and I would ask that you check back in when it is up and running. Also, it is totally coincidence that I stumbled across this post in the forum, so sorry for the late feedback.
