Thanks for the reply. I also discovered that if I download the app, one can have both business and personal accounts open at the same time. That can be done by a menu item under "File."
When using the Evernote app, i can have my Business (company) Evernote open and my Personal Evernote open and can toggle back and forth between them. In the Web version, the only thing I can find to do is sign out of one and then sign in to the other. It would be great to be able to have two tabs open; one for each.
