SWC is a triannual virtual writing camp. It runs for the whole month of March, and you make a word goal for yourself, and try to reach that by the end of camp. There's also a competitive aspect with cabin points (you'll be in one of 11 or 12 cabins), and you can do activities such as word sprints or word crawls for points. The camp goes from the 1st of March to the 31st of March, and it's online so you can be there 5 minutes or 3 hours a day, at any time.
