For Lynne in Sydney, Dear Lynne, I am so sorry it has taken me so long to acknowledge your email and thank you so much for all the information you sent it really is helpful and much appreciated. My computer has been acting silly and have had to wait for my son to come and sort it for me. Hopefully all is well now. Christmas is taking over a little now so I hope to get back to my research after the festivities and your information will be so help, thank you again. Trust you will have a happy and peaceful Christmas and New Year - probably on the beach, yes? My regards, Elaine
