My conclusion was that for even relatively big languages like Catalan it
is
impossible to get representation in community elections unless you start writing in English Wikipedia.
Well, if I remember correctly, at some point we elected an Italian board member in the community elections. (I do not even mention a French member and a German/Chinese member, since it is easy to argue that these are major languages). It all very much depends on the candidates individually and on the set of the candidates. This does not invalidate your point (and I personally believe that we need other avenues of elections that the direct community elections), but is intended to put the argument in a good perspective.
