As for presenting WikiTree as a whole in different languages, the Dutch Roots Project and now if I'm correct the Sweden Project is planning on starting one as well ,so some of the so called ''Roots'' projects are already working on Language Portals , a very enthusiastic group of members from the Dutch Roots Project for example is already working very hard on the Nederlands Portaal .
When it's finished all Dutch (reading) Wikitree members can learn and read all about Wikitree in their own language. We are translating almost everything in Dutch to make sure all members that understand, speak and or can read Dutch have a place where all is explained.
We started this as a sub project of the Dutch Roots Project, but these Portals of course also fall under the Global Community Outreach , Language Volunteers, and under the Language Project where already different Portals (we of course hope more will follow ! :) ) can be added see: Language Portals There you also will find Different Languages used for profiles .
So we hope Wikitree in time will have Portals for members from all different countries, that would be really awesome and make it more easy for members from all over the world to join :)
