Hi,
As you may know, HTTPS will be activated today on the Wikimedia projects
(for logged-in users). There is a dedicated page for the support, which
can be translated and linked in the central notice (you may want to update
its link once translated):
http://meta.wikimedia.org/wiki/HTTPS
I’m not sure it is a good idea to activate the Translate extension because
the page is not very stable and it would result of frequent returns to the
English version (but if you have work-arounds it can be done). For now it
are only manual translations (done for Italian and French).
A short message on the Village Pumps was also distributed by Greg
Grossmeier, you may want to translate it.
Thanks,
