These are the URLs for the UK sites KarenG mentioned.
1)Royal College of Nursing-http://www.rcn.org.uk
2)South Bank University-http://www.sbu.ac.uk/health
And here are two more,which between them should get you to all the universities which run nursing related programs.
3)Nursing and Midwifery Admissions Service
4)Universities and Colleges Admissions Services
I realise you are not trying to get on a course! I am just including the last 2 sites because they are the only places I can think of which list all the places which have schools/deparments of nursing. you may have to search a bit,but you should be able to find online addresses for all.
