-Every user of a services app has two unique identifiers: a username by which they identify themselves, and a userid by which they are identified in persistent storage.  The username may be mutable and is selected by the user; the userid is immutable and is generated automatically.
+Every user of a services app has the following unique identifiers:
+* an email address by which they identify themselves, and
+* a username, formed by taking the sha1 hash of the email address, and
+* a numeric userid by which they are identified in persistent storage.
+The email address may be mutable and is selected by the user; the userid is immutable and is generated automatically.
 In code, the user is represented by a dict of their user data.  It will always include the keys "username" and "userid".  Applications may also arrange for other keys to be loaded into this dict.
