I believe that all the profiles that find its way to his project should be Master Profiles - for historical and genealogical purposes. Some of them already are, and have really nice profiles.
The list of not-yet-MP profiles:
Leka II, titular King of the Albanians
Luis Alfonso Jaime Marcelino Manuel Víctor María de Borbón y Martínez-Bordiú, Duc de Anjou
Vittorio Emanuele, principe di Napoli
Nicholas, Crown Prince of Montenegro
Rüdiger, Markgraf von Meißen
Grand Duchess Maria of Russia
Prince Nikolai Romanovich Romanov, of Russia
What can be done in order to make these profiles MP, how could I help that (with no possilbility to view or edit these profiles)?
All of those profiles have English Wikipedia websites, as follows:
I hope it's helpful. Please write whether you need more information from me.
Karol, you're doing phenomenal work on this project. Thank you for all your efforts.
You'll need a curator to MP profiles. Since I don't typically work on royals (or pretenders :)), I'll leave it to someone else. You currently have the following curators as members of the project: Justin Swanstrom (taking a break), Günther Kipp, and Private User.
