Elizabeth Barton mentioned on her blog on the 26th that she was going to be doing an online class - no details yet. She is coming to the UK in August so I am hoping to be able to get to her 2 day class then. Go here to read what she has to say. http://elizabethbarton.blogspot.com/2010/01/paperwork-paperwork.html
Sorry there doesn't seem to be the facility for adding the link to go straight to her blog. Maggi
