While you can switch an existing course back and forth between the various course formats it is HIGHLY suggested that you DO NOT.
The course format is not designed to be organized like topic or weekly formats. This is a conversation, a timeline, a social stream of learning.
If using this do not use an existing course and switch to Socialwall. It is not designed for that.
The idea is that if a teacher starts with socialwall they may build blended learning skills and migrate or progress to a more traditional course format/structure. In which case, the socialwall course format can be switched to topic format and then organized without the teacher loosing all their work from socialwall.
