User Name and E-Mail Address

What is the difference between my username and my e-mail address?

Do I have to use mail.tqci.net, or can I use tqci.net?

What is my E-Mail address?

Any e-mail address on the Internet consists of 2 things - a username and a domain name. For example, if my username is joe and my domain is tqci.net, my e-mail address would be joe@tqci.net

Just as in the example above, you will use your username that you chose when you signed up for service, and our domain, which is tqci.net. End result being your username@tqci.net

You can use your username@mail.tqci.net or your username@tqci.net - either one will work.
