Name is to hold your real name and eMail should contain your regular eMail address. As some internet providers change this address in outgoing messages, you can provide a second address to which answers by eMail should be sent. Just enter that address in the Reply to field.

Some providers insert their own name here unless you specify one yourself (very few providers have the nerve to replace your text with their own). To do so, enter your organization description into the field Organization.
The text entered into the Signature field is put under each new news message you write by BeInformed. It should not be longer than four lines.
Close will close the dialog without saving the changes, while Save saves only the changes you made in this tab view. If you select another tab and then close the dialog, changes in other tabs will be lost unless you save them separately.
