How can I change the Username for our organization?

I set up this account as a test, using my own personal name as a username. Now that we have a paid account and are starting to use this program for our organization, I would like to change it. Our admin team will need to access the application and we would prefer to have a username such as: GenChurchAZ or something to that effect.

We can change your username for you.  Let us know a few of your top choices, in order of preference and if it is available, we will make the change.
