Last week, I volunteered at the public library with my buddy Clark. We were cataloging donated books, so I shared a spreadsheet with him at firstname.lastname@example.org. Little did I know, he was already into Docs & Spreadsheets, but typically used his other email address, email@example.com, to log in. Luckily, with the new invitation system, it worked seamlessly. He could see the book sale spreadsheet right next to the documents he'd already been working with.
Many of you shared your concerns about the old invitation system: needing to invite people on a mailing list, or having problems inviting users who had multiple addresses and multiple Google Accounts. So we've simplified our invitations to work better in those cases. Now, if you set the "Invitations may be used by anyone" option, the people you invite can get into the doc from whichever Google account they prefer - even if they aren't trying to hide a secret identity ;)
