I've been doing this for two years (following a consultants project). I never noticed the Signature variable type. I dropped it on the form but thought there would be something more self explanatory about it.
Can someone share how this works beyond just creating a new memo type? I can easily add a button that sets the "signature" value to the user's name. But... why do I need a special "signature" variable type for that?
Please help.
