Hi guys, thanks so much for your involvement; I now only need to have the strings translated into Chinese -- so if you speak this language, or know someone who does, please let them know I'm seeking their help :-)
@Takeshi: Have a look at https://ja.planet.wikimedia.org/ -- the planet logo comes after the phrase. At https://bugzilla.wikimedia.org/show_bug.cgi?id=56412#c5 Kzhr suggested to leave the phrase untranslated, what do you think?
Again, thanks so much for your help! Tomasz
