Let's first see where this is going. If you have a different source for your 500 nouns than where my 5000 words come from, then it would mean adding them to the 5000 word spreadsheet by hand. If it is the same it could be as easy as copy and paste.

You can always send me the file by PM to robinpfeifer -at- web.de and I can find out whether I can integrate it.
