I need to change the email on my account and ideally the account name for my account

Both the email and account name were put in by a different employee at my company. Please help me make this adjustment so that receipt are sent to the correct place. 

I would like the email to be leadership@dallaschamber.org and the login to be the email the same as well. 

We have changed the username as leadership@dallaschamber.org , please go ahead and go using the same password into the Account > Settings and you will be able to update the email address.
