Allow multiple users to access a single account

I would like to allow other people in my organization to see stats, bounces, etc.. in the sendgrid account.

My use case is a single sendgrid account that is used to send and receive email for a web application. I would like to give each person on the dev team a separate login for Sendgrid so that they can see activity in the account. These "web-only" accounts don't need to be able to send mail, just see the web interface at sendgrid.com for a given account.
