I need to get the card email from a variable because i want to make a rulle that when someone is named in a card comment thisone (external person, not a member of the board) receive a mail with the comment detail (i already done this) and the card email so this person could answer by email and it is added automatically to the card as a new comment.
I know that by using the share button I can get de email, but what i really want is include this in a rule through a variable.
