Is there a way to enable form pre-fill for anyone that is in our Marketo instance that lands on gated content? The overall goal is to help people that are already in our system not have to put in their information time and time again to download content.
Ah, good point, Jay.
Virginia, while it isn't the same as Pre-Fill -- it can only show First Name and Last Name -- Known Visitor HTML ("If Known Visitor, show Custom HTML" in Form Editor » Setup) also streamlines the experience for people who already have an associated Munchkin session.
Of course if you want the lead to be able to view and modify their existing values, they can't with KV HTML.
