Sometimes it is hard to log in because your browser is using a cached version of the page.
To get around this, use an incognito window (Chrome).
Click on the three dots in the upper right hand corner and choose ‘new incognito window’. Then go to the CAFCN website (cafcn.ca) and click on the green button on the home page (scroll down until you see it) to get to the login page for the conference.
