Last time I checked in September (see
Analysis - Ranked-up Users Section/Subsection profile (& Local Boards)), I counted only 2 people who has managed to rank-up at least one level (>=Member) under the Merit System in the Dutch board, purely receiving all the required sMerit on the local board. An additional 5 that had done so receiving the required sMerit both on the local Dutch board, and other general English boards. Of course I do not have a reference to those that post and get merited solely on the English sections of the forum.
I just had a look and found most Dutch local board users that had received merits received them on the German board and Main board.
Most Dutch people have learned English, German and French in addition to Dutch. Spanish and Italian is relatively common too.
