I have seen in a pre-sales question (http://forum.gravityhelp.com/topic/features) that Gravity Forms has the ability to "auto-populate a field with the username of a logged in user. There are some variables you can use for default values that include the users email, users login, users display name, etc."
Where do I find these variables? I would like to auto populate the user's name and email address, but can't seem to find this anywhere in the documentation.
Please help.
