Whats the difference between “username” and “account name”?
Username is the “name” by which you are known to Dragonfire; you use your username (and password) when connecting to Dragonfire to upload to or download from your account, or when requesting changes in your account. Account name is the name by which you are known to the rest of the world; the account name is used in web and anonymous FTP URLs and E-mail addresses.
