+1 - This would be a great feature! I just came on board with using Evernote to organize as much of my life (business and personal) as possible, and this was one of the first features I looked for. I was rather surprised that the only options were: 1. Mix my business and personal collaboration via one email. 2. Create multiple accounts (1 for business and 1 for personal). I own my own business with multiple clients and the first option is not viable for me. My personal email has a whole different public face than my business email. (My personal email is used for blogging and connecting with others of similar interests, and my business is unrelated and would confuse my clients if they found it related to my personal profile) Since I am forced into option 2, I now have to decide with which account do I want to purchase premium. At this point it would be a bit overkill to pay for two accounts. I don't need that much bandwidth yet, and I want to be as frugal as possible. However, not having premium for either business or personal I could see needing to expand as activity increases in use of this great tool. There are a lot of services out there that benefit my business greatly, and I cannot justify paying for all of them, so I must choose wisely. So far I do love what I see with Evernote! Way to go developers, and creatives! You have really built something great! Thanks for taking the time to read my input.
