Hi Martyn,

Removing PPP from all not notable post 1811 profiles managed by the Netherlands project

As a first step in our quest for a more managable list of project managed profiles. We are going to review all post 1811 Project Protected Profiles. Every profile from this period which is not a notable profile will lose it's PPP-status.

Our reason for this measure is to get a list which conforms to the WikiTree rules for PPP's (wikitree uses a 200 years limit) We use 1811 becausee it is the start of the civil registration.

As one of the co-leaders of the European Aristocrats project, I'm messaging to inform you that we are removing the "House Assignments" from our project structure. You are absolutely still welcome to work on the profiles from the families that you chose, we are simply removing the official House Assignments as, for the most part, people choose to work on whichever profiles interest them. We're glad to have you in the project and we hope that you continue to work with us!

Regards, Amy Utting

Hi Martyn,

We have a fairly new volunteer whose tags and comments are all in German. He's not made in contributions since joining. Would you welcome Karsten Kube to WikiTree and let him know that help is available.

I would like to invite you to join Space:Austria project It is a new project i am get started. I noticed that you were already Manage the Central Europe project, and thought you might be interested. When I requested a template and badge Abby (Brown) Glann indicated I needed a leader to work under, and you seem to be the most logical.

Thank You
