I refer in the screencast to SqueakMap, that is map.squeak.org/ . When you register an account there you specify your initials which becomes your primary account name. SqueakMap ensures they are unique. Then you will be listed along with other Squeak developers at map.squeak.org/accountsbyname . Specify the same initials when asked your author initials in Squeak (Note that SqueakMap may force you to adjust them in some way because they are already in use, annoying but unavoidable, be sure whatever you end up specifying on SqueakMap is also used here.) then whenever you modify or add a method your author initials are noted in the method annotation and if someone has a question about a method they can identify who created it or recently modified it and track it back to a name and email address on SqueakMap.
