Clicking Dashboard -> Send invitation -> Get invite link does not do anything.
After I open my Dashboard at dashboard.duolingo.com, the page tells me I have no students. I click Send invitation, fill in the section name, click Get invite, but nothing happens.
Students can add me from their settings, that does work. I'd like to use the invite system, though.
What does not work is clicking on the generated URL as a student. Dashboard gives me an url like https://firstname.lastname@example.org. If a student clicks it, the "Uloži změny" button is grayed out. It activates only after they make a change in the two form fields.
I am using Chromium Version 39.0.2171.95 (64-bit) although I guess this is just a simple lack of foresight on the part of Duolingo web developers, who did not realize that the form might be ready to be submitted without the student actually typing in anything, not a browser error.
(I tried all this with the actual link containing my actual e-mail address first and got identical results.)
