First, select the My Labs tab at the top of the page - then click Manage.
From this page you will be able to manage your Labs.
You will be brought to a page that houses all your labs. In order to edit your lab, simply click the green Manage button. A drop down menu will appear, click Edit.
You will then be redirected to the 'Edit Lab' page. This page functions nearly identically to the 'Create Lab' page, in that it displays all of the information that you are able to edit, modify, and save. Work your way down the form and edit as much information as you would like.
At the bottom of the page you will see Cancel, Save Lab and Continue buttons. Click Save Lab in order to save all your changes. Once you click Save Lab, you will be redirected to the Lab presentation page and you will receive a confirmation message that the Lab was successfully updated.
