How do I switch between workspaces?

Each workspace has its own address (for example acme.deskhero.com), so you can simply open the other workspace's URL in your browser. Alternatively, sign in from the general sign-in page. When your account has multiple workspaces you get the "Select your workspace" page and can pick the one to enter. Your profile page also lists everything under "My workspaces", with your current one badged "Current workspace".
