Go to the "members section".
scroll down below all the navigation links, and you'll see a subheading about CPD.
within the next block of text is a link to "enter you CPD points on line".
follow that link, and scroll down past all the navigation links, and you'll see first a list of all those it knows about already, and then a form to enter new ones.
Have the list handy before you start, and be areful, because if you make a mistake, you can't yet correct the entry.
