In the Account Settings tab, you can see and change the general information regarding your Ustream Align account. This is different from the Channel Settings tab in that the Account Settings tab deals with your subscription type, billing information, and account password as opposed to details about your Ustream channel.
The second tab under Account is the Account Settings tab. This tab allows you to change the basic information about who's name is on the account, and how to access it. On this tab you can change the first and last name of the primary account user, the email address associated with the account, and the location of the primary account user.
At the bottom of the page, you can also change the password associated with the account, or delete the account. Please note that in order to change the password assoicated with the account, a user must know the current password. If you do not, you will want to click the 'forgot my password' link in the login popup on www.ustream.tv.
