Here's a video about Anvill.
So I decided to open a teacher account and to create a course in Anvill. You don't need to request for membership. The course is called "Trying ANVILL: Materials Desing" (Group Registration Key: 2447) and is open as you can see in the above screen shots.
Then I created a lesson plan based on a presentation by Nik Peachey delivered at IATEFL 2013. After watching the presentation, students have to complete certain tasks. As a follow up activities I created a voiceboard and a forum.
