I owe everyone an apology for giving out duff information. I AM wrong in my interpretation as I discovered when my Disclosure was returned by the Embassy today. They sent with it, a bulletin highlighting what I should have done. This link tells you what to do.

Sincere apologies to anyone who have already sent postal orders to the Embassy. All is not lost as you can cash them in yourself.
