During an informal discussion with users, someone expressed an interest in posting anonymously on the Stan user list. The reasons were:
1) feeling more comfortable asking 'dumb' questions (that person's questions were not dumb at all)
2) avoid giving away email address and being subject to harassment because of asked question, gender, etc.
What do people think? Seeing this has worked on Stack Overflow, I think we should consider adding the feature to the user list.
