How do I change my username?

[JoeyJones]

My sign in username is an old email address and I cannot figure out how to change it. I've located how to change my password, but not my username. Please help!

@JoeyJones you are not allowed to change your username. Only your site administrator can do that.

Hello,

I'm to new this Forum and to SAP CONCUR itself.

I'm a little confused by the above answer.

Who's site administrator, SAP CONCURs, my website administrator or the Company I do occasional work for's website administrators?

Many Thanks.

@irmuk every company that is an SAP Concur customer has at least one of their employees who is designated as the SAP Concur site administrator. That is what I was referring to in my answer. 

SAP Concur is referred to in two ways; 1. The company itself and 2. the website where you do your expense reporting and/or travel bookings.
