Hi threecats
My advice is to write something, and that is based on feedback that we have received from a small number of members who have had the form. The majority thought that it was best to write a couple of sentences at least for each of the three questions, even if you are confirming that nothing has changed. A couple of people felt that they were at a disadvantage writing nothing.
