Switching between groups in LiveWhale is allowed only if you are an administrator, or if an administrator has assigned permission to switch to a particular set of groups.
From the LiveWhale interface, the name of your group will appear next to your name at the top righthand corner of the screen.
Click the group title. A dropdown menu will appear in which you are able to select from any of the groups you can switch to.
Select the group you wish to switch to. You will switch into that group, retaining your same user identity. Upon switching, LiveWhale will try to take you to the same page you switched from.
