Ah, well spotted.

I've just tried to create a translatable title using the syntax of the licence link below this, but failed to get the syntax right. The question is, do we actually need titles here at all? If you look at the file, you'll see there are already a lot of untranslatable titles in there - these are left over from the old project site and haven't yet been made translatable. 

If we do need to retain the titles, I'll need some help in getting the syntax right, and I'll then fix them all. If we can drop the titles, this would make things easier, and I'll remove them all.

I'd vote for dropping them - they only bring up tooltips, which aren't really more informative than the link text already visible. But if you feel we need them, I'll do what I can to make them translatable.
