We are a print house that uses a Trello board for order tracking and workflow. We need tha capability to give the client a link to just one card (we don't want them looking at everyone elses projects), so that they can do proofing and add comments on just that one card.
We cannot force them, nor would we wish, to have them part of our Trello group.
Is this still not possible in Trello? Is the only solution a card-to-email/email-back-to-card route?
This is really keeping us from using Trello effectively... and the extra steps between card-email-card leave lots of space for lost data (delayed printing for us), as well as extra data entry for my team (loss of hours and productivity while copying data).
