Hi
Sorry, but they are written in German. Another point is, that you have to be aware that there are a lot of editors that are logged in via en:Wikipedia:Unified login. In my findings from 267 new editors, coming in via Unified login, 255 never ever edited. At "Account Creation Improvement Project" you will find, that in the German WP there are 579 new user accounts average per day. That means, half of them are Unified login editors which are indeed experienced users from another project (not new editors).
That was me who deleted my link of the list on the frontside of this page. Sorry, I forgot to login.
No problem, and I will ask around to see what the implications of Unified Login are (I assume that it means your userid will be identical across Wikipedia's but let me check).
Maybe bots that are linking articles between different project have an implication on this study. You could detect them via Unified Login, because there you can see which is the home wiki. Or you are able to see if a user has a bot flag, but I don´t know if every bot has a bot flag.
By the way, in your definition of New Wikipedians and Active Editors you don´t say anything about bots and editors with a different home wiki.
