Trying to follow directions, but still can't find the Unresponsive Profile Manager Form on the PM's page. Her last contribution was in 2015, so she may not be around at all anymore. And I can't see the unlisted profile that I am wanting to mark deceased to even see if there is an Unresponsive Profile form on it.
Found another person with a similar problem though, followed a link from that response, and just changed the name in the URL. That worked!
