Drawpile just came out with a bunch of new features, most happily: public session listings!
This means no more having to manually enter ip addresses; you can simply go to Session > Join > Find to locate a drawing room!
I'll stream a session for a while tonight. The room is called HexadoodleHQ. Read the instructions before joining! www.furaffinity.net/journal/57…
Or if you just want to watch, you can watch the stream here: furstre.am/stream/hexadoodle
