*NB This might be a good time to create your Personal Diary if you haven’t yet got one. To do that go to Personal Diaries (which navigates to that Category) and hit + New Topic and it will create a new Topic with the special pro-forma. Don’t delete the contents area and don’t delete the bold stuff. I will make your first post a Wiki so you can keep your summary up to date on an ongoing basis. Ping me if I forget!
