To log in:-
The normal editor password is Ruttsborough's forename, in lower case.
(By the way, for those people with full admin access, the admin password that you received by email also has not changed, and admin access also includes editor access anyway, so you don't even need to work out the editor password above.)
Your username and editing privileges will then be stored in a cookie on your browser - you shouldn't have to log in again on the same machine. Unless, that is, you regularly clear out all your cookies.
(If anyone's having trouble logging in, contact "kevan" at "kevan.org".)
