As far as I know, the burden on active members of WikiTree to 'discover' if non-active members are alive and are participating on WikiTree requires four steps: Trusted list request, profile comment contact please, private contact please, then an unresponsive contact form. Yes, please do correct me if I am wrong about this four step process.
Now if a project sticker, such as {{please contact}}, could be put on profiles managed by people who have been gone-gone from WikiTree for a 'long-time,' or something equally as simple, I'd be willing to do that.
The purpose of this question: "Re-greeters Project may release burden on WikiTree-active Profile Managers (PMs)?" is to properly frame the question. How would you 'pose' the intent of the question (to release the burden)? How would you then answer your question?
This question will stay active for at least 10 days (9/21 EST), then the answer with the most up-votes will be chosen as best answer.
