Trello is about perfect for my basic organizational needs, but I can't come up with a solution on how to share card information with an outside user. I'm tracking questions/issues and when done I'd like to be able to send the results (without cutting and pasting) to an outside email. Any solution?
Alternatively, if you're okay with the end user seeing the Trello card in a different format (like in an email) I might recommend trying Zapier.
You could set up a new Trello List on your Board called "Shared". Then, use a Trello to GMail Zap which watches this new List for new Cards.
When Zapier sees a new Card in your Shared List, it can automatically send the contents of the Card in an email.
You might consider putting the outside user's email address into the description field of the Trello card and mapping that over when you build your Zap. If you decide to do this, keep in mind you'll want to add the email address before putting the card into the Shared List.
From the Trello help guide:
So it sounds like the only way to do this is to make your board public and share the link right now.
