Claus, I started work yesterday on updating the category language lists to the new format, so that new translators won't get off on the wrong foot. I'm aware that it will outdate existing translated pages, so as soon as I've finished updating those lists I'll pick up the Category pages to get lists of pages using the older format, and make the change to the new one. I don't want to create too much work for everyone else. Hope that's OK for you.
I see that you've already done lots of the pages - sorry I didn't get this written last night
No problem, it didn't take too long. In the process I noticed, that the Gluon page has no category. I would have added one, but was not quite sure how: when making a new section in an existing page, should I leave out the unit number tag and let the translation system generate it, or does this only work when marking up a new page?
