From "How do I change the name for "teacher" in the course description?" I imply that we will have to wait until we upgrade to 1.9 to be able again easily to have a teacher eg "Mrs Bloggs, Head of Year 10" or for another course "Mrs Bloggs, Head of Chemistry".
It could be done now by creating multiple roles all with the same permissions as teachers but that would quickly become overwhelming!
Thanks again - it has saved me spending too much time looking
