If you need to be part of more than one office, this is possible with the profile switcher functionality. If you have more than one user account tied to the same email address, you can switch between the accounts by doing the following:
1. Click on your name on the top right-hand side
2. *If you are a part of multiple offices* you will have a drop-down list appear that looks like this:
3. Click on the profile you wish to be logged into and the system will switch you from your current office to the next office
NOTE FOR SYSTEM ADMINISTRATORS: When creating multiple accounts, it may be good to change the username to the location so that the profile switcher dispays it and it's easy to distinguish which profile is part of which office - for example "bsmith-Vancouver"
