due to my ignorance of German (which is my fault, of course!)
I wouldn't say that. German...
a) is quite difficult
b) is not the most popular language around
c) sounds hard or even ugly to many people hearing (but not understanding) it
d) learning English (as a foreign language) is usually way more important / useful
... so I'm usually very impressed by any "foreigner" actually bothering to learn speaking/understanding it at all. Not knowing it, however, is nothing that anyone should feel troubled about. Ever.
Now, about translations... I'll sure help. But since I don't have that much time that I'd like to spend on it, I'd like to stick to
translating - i.e. I don't want to bother copying content from a German page to an English page or creating an English page from the roots, etc... (As I have no idea about tiki-wiki... and not much more about media-wiki, too). So if someone gives me an "English" wiki page (just with copied German content) I could go and start translating that (=I'd just translate the text parts, leaving the formatting as it was, since I don't know how to do that for example). Of course it would also be helpful if, like Dwachs said, people would tell "us" Germans what pages are "urgent" for them - since nobody will probably want to do it all at once (I certainly don't).
