Ivan, I have used Evernote Account Switcher myself. Generally, it has worked well, although one time I ended up with a mixture of notebooks from two different accounts after using Switcher. What I need to know is if a group of us can successfully use one premium account.

It works great. They are always insync and happy." My team at work would like to do the same thing: one account that can be accessed on multiple computers. We would like to know if different team members can access the same notes at the same time while working with Evernote on their computers (rather than via the web).
