There are a couple of mistakes and I dont know how to contact the person who did it.
suitable - geeignet (not geignet)
wrought (not wrougth) iron - Schweißstahl
Its really annoying that you cant just contact them directly.
How is anyone ever supposed to find this???
We are all going to try to help you…
I have put your thread in the English section, can you please give us a link to the course ?
So that we can identify the course creator and ask Memrise staff to check if that person is still active or perhaps on this forum
Cool. Thanks so much.
Here’s the link (not sure of thats the one you wanted):
http://www.memrise.com/course/122243/englisch-fur-ingenieure-2/
And the course creator is:
stefan8277
I remember trying to contact the creator in the old forum… i dont think @stefan8277 is active on memrise anymore, i think he’s been absent for years now
@Lien are you still able to help with finding stefan8277, or did I read that someone else would muck in ? 
ahmmmm… like…the moderators???@MemriseMatty was the contact person now? or @Joshua , or @OliviaZavala… I don’t know the other nicks in the “moderators” list
@alexandrastirnberg We have now added you as a contributor to the course. You can now correct these 2 translation errors - http://feedback.memrise.com/knowledgebase/articles/525167-add-a-contributor-to-my-course
Thank you so much. However, I somehow haven’t been added to “English für Ingenieure” but to “Anfänger Spanisch Teil 1”.
I can see if I can find mistakes in that one too ;), but for now that does not help me that much.
Apologies, This should now be updated. Thanks
