This is starting to get frustrating. I am sharing research and info with other students, which leads to a lot of shared notes and tags. We use the work around that the owner creates tags for everyone, but here is where it gets painful: the tag hierarchy. I have about 200 authors on about 35 topics in my 3000ish notes. When someone shares with me their research, I cannot add their tags into my hierarchy, and they cannot add mine to theirs, even if we have the same tags! Instead I have a single layer list of unorganized tags with their user name appended on the end, and no way to pile them into categories like "author," "theory," or "research" etc. If evernote is about sharing and collaboration, this seems like something that should be fixed.
