Black-Board or Market-Place for "I look for" "I offer"
Probably it already existists, but I have not yet found it.
I am a native German speaker and would be glad to correct/coach learners of German for approx. 1 hour a week.
Where would I post such an offer? Where would I find inquiries of Germans-students looking for support?
One problem is that there is no way for private communication through DL at the moment. And posting your private contact information is not smart and also against the rules.
You could maybe post once a week and offer your help, and learners could post their questions, short pieces of writing, etc. for correction and feedback. I am sure lots of people would love that. Or you could give short assignments for a more structural approach.
