Before you sent the Unresponsive Form, did you do all 3 things requested - Private message to the PM, message on their profile, and request trusted list?
Has the person been active on wikitree? if not and you submitted the form more than a week or so ago, I would send a note to info @wikitree.com to see if there is something that you need to do. Make sure you include the Wikitree ID and when you sent the form. Paul will probably respond with a reason for delay, maybe he has been busy or away himself.
