OK, here are the results!

Docling Europe + Asia Writing Group
Time: 6-8 AM GMT every Wednesday, starting December 23rd

Notes: What?! Where did the North America + Asia group go? No one from North America filled out this link, but Andrew (Africa) did, so I have switched it to Europe/Africa + Asia/Australia. We can try again to set up a NA + Asia group if there is interest, though.
Format
At the beginning of each writing/working group meeting we say hello and chat for a few minutes while everyone joins the meeting. A few minutes after the start, we go around and each person shares what they have been working on during the past seven days and what they plan to work on during the two-hour session. After everyone has done this, we begin working silently until 10 minutes before the end of the two-hour period. You can turn your video off or leave it on if you want to. We then reconvene and share our progress during the two-hour period and what we hope to work on during the week. That’s it!
The groups can be relatively open for new participants. Above a certain number of people (~7 or 8) it becomes easier to break into smaller groups, which we can do easily in Gather.
