The largest online community of writers using the Modern SignWriting symbolset and encoding.
Writers from around the world have joined Valerie Sutton’s open culture initiative.
The writing is mostly under Creative Commons by-sa, except where explicitly stated elsewhere. One exception includes all of the private puddles on SignPuddle Online which are not explicitly CC by-sa. Valerie Sutton or Steve Slevinski should be able to answer or direct any license questions.
SignPuddle Online is hosted by the Center for Sutton Movement Writing on a DeafVision server. The closed source SignPuddle Server code uses the open source SignPuddle tools.
