Update Config cards and account documentation+issues

I saw that the *signup card has disappeared from a couple of Wagns - and English. Also, the *request card is now blank. Figured out what has happened and it seems like:

• *request should be deleted from English.
• Existing Wagns' Config card should be migrated to match English.
• accounts should be updated to reflect the name change from "Account Request" to "Sign Up" (and tangentially to explain the stuff about tokens - I have no idea how that works).

I understand wanting to simplify Config, but it is now much harder to discover how to configure things around accounts. Maybe at least include on Config the fields for customizing the default setup around accounts (such as setting what email address receives notice of new Sign Ups)?
