Issues with German Translation

[etsde]

There are many issues in the German translation, such as:

"...würde ein ganzes Land mit 1 Million Einwohnern..."

which should actually mean:

"...würde ein ganzes Land mit einer Millionen Einwohnern..."

or

"...Vergesse nicht, alle Benutzerkonten..."

which should mean:

"...Vergiss nicht, alle Benutzerkonten..."

And in general there is used an inconsistent translation with "Sie/Du". May I know where the website strings are stored? I would be happy to fix it.
