The Login procedure has changed a little.
To Login to the system on a desktop or tablet:
Click on the Login menu item on the right of the lower menu (to the right of Website Registration).

To Login to the system on a phone:
Click on the Login menu item in the Mobile menu (just below Tutors). Click the 3-bars icon at top of screen to view the mobile menu.

That will take you to a landing page with the sidebar menu showing. If you find yourself on a page with no side menu, just click the Login button again and you will go to the landing page with side menu. If you have logged in already, you won't need to login again. (On a phone, the sidenar menu is displayed below the page content, because of the limited space available).
You are not currently logged in.
