I worked to the through the review list of the LibreOffice extensions and templates website and managed to look at the remaining projects. I sent hints to the contributors and am looking for their project site changes and updates of their release files.
I fixed some string issues inside one of the Plone add-ons that we use to drive the website. I got to this issue by an error message inside the website log. The fixes are available in the TDF Github repository yet.
