- One is a group for students and former students of the MA Mysticism and Western Esotericism in Amsterdam (Western Esotericism MA).
- The other, playfully called The Grand Lodge, is for scholars of Western Esotericism more generally, excluding university teachers and professors (for reasons of social ease and liberty of speech).
Both groups are accessible through facebook friends.
Those interested in joining one of the groups must have or create a facebook account. Then they can send a friend request to someone who is already a member, such as Ward (Eduard) ten Houten or myself, including a brief message stating they would like to join the particular group. You can find us in the facebook search engine under our full names.
