But in those sister projects communities, I have met
fierce resistance
to any new branding or technical rearrangement. They even tend to
avoid to associate themselves with Wikipedia. They want to grow on
their own appeal and strengh. (They also are annoyed when Wikipedians
come to a sister project and don't learn immediately that the rules
differ.)
And with good reason.
