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, ~ Seb35
