What do you mean with "should we list here?" This is a complete site for the German Snitz version. He is supplying all info in German, like links to the GPL, supported databases etc. He also offers a German version for download. As far as I can see (didn't download, but looked at the support forums) all credits are still there, the link back is very visible, and he makes it clear enough that he just did the translation. He doesn't offer the English version for download, but links back to here for that.
The only thing you migh consider as being "bad" is that because his site is so complete, people might think it is affiliated with Snitz.com instead of an onofficial German version support site. So that would be one thing we might ask him to make (even) more clear.
