I mainly use it as an english dictionary of math terminology.

Although for the basics of differential geometry like the Weingarten equations and the Dupin indicatrix WA is lacking - as is Wikipedia except for the articles in the german Wikipedia. And I haven't found a way to get to the 'Weingarten equations' searching for 'Weingarten', you only find him by the full name 'Julius Weingarten'. :(

If only there was some way to contribute to the english wiki (article or search) when you are lucky enough to understand the (better) german one...

That's a bit recursive. I'd have needed english translations of the german articles to get to know the english math terms to be able to write about them in english :)

Maybe the German wiki pages on the specific math terms are already translated to English. If not maybe google can help.

Not saying it's easy.
