I've taken a closer look at it. There's a French site, which apparently contains all the information and stuff, but I don't speak French, so it's incomprehensible to me; and apparently these people have German friends - who decided to expand the organisation's activity into Germany. The author of the German part is probably not one of these, though, at least as far as I can tell from the way it's written. Not much information there, just a list of the org's members and some photos of their first successful expedition.
