I don't know if this is the correct place to post this. If I'm wrong, please let me know. :-)

I just found a small error in the skill tips and notes for "Verbs Present 1": https://www.duolingo.com/skill/de/Verbs%3A-Present-1/tips-and-notes

In the right column it says: "In addition, when a verb stem ends in -s, second and third person plural forms will look the same:"

This should be "second and third person singular forms...".

Thanks for a great course!
