Hi Uli,
Welcome! We’re pretty low ceremony here. The idea is to write (at least) 2 pages per day. Every day we have a new thread for the day where you can post that day’s progress. Every Friday we have a page count checkin, where you can talk about your progress, successes, and struggles for the week.
Ask questions anytime – come here for advice, ideas, and writing tips. You can also participate via Twitter @pragprowrimo.
Looking forward to hearing about your progress!
