You may have noticed the the old 'login' box is no longer on the left on your screen. It has been replaced by a floating image that has two elements.
On the top (the 'head') is the login box. After login, scroll down to the bottom of the page, where you will see your profile picture. Click on that to edit your profile and manage your connections.

Below that, the + sign takes you to the 'join EAS' page, where you can quickly and easily become a member.
