I've noticed that when using Google Chrome, the main Mahara menu is collapsed, which is not very intuitive (here's an image):
If you're like me and would rather see the menu, then I suggest using Safari--the full menu appears for me.
Of course, if your version of Google Chrome doesn't look like this, then consider yourself blessed and continue using Chrome. I'm still fiddling around with settings and extensions in Chrome to try to figure out what is causing this . . . If anyone has figured this out, I will buy you a cup of coffee or maybe even a chai latte.
