Let's have a weekly meetup where we briefly present to the rest of the group what we have learned about writing in the last week (or where we are stuck---maybe someone can help you out!), followed by focused writing for an hour, then a brief feedback round, and then an open session :)
So, you get something done (yay!), get feedback (also yay!), and have the possibility to share your knowledge about writing :)
Language is German or English, depending on the people :) Other genres are welcome, too, although the focus will be Science Fiction.
