There are a few ways to add multiple locations to your Alignable Profile.
You can always write the addresses of your additional locations in your "About Us" section on your profile.
Another option is to create separate accounts for each location.
To do this, simply log out of your current account by clicking on your name in the upper right corner and clicking "Logout".
Then, go to alignable.com and instead of logging in, click "Don't have an account? Create one".
Follow the process for creating an account. Be sure to use a unique email address for your additional location.
