Star Cards

Some card names begin with a star (*). These "star cards" are

referred to in Wagn's code, and/or
key to Wagn's default structure

Note that *title and title are two different cards -- the star leaves the name for other uses. Also see an alphabetical list of all star cards.

Rules

Wagn configuration works by connecting Sets (groups) of cards to Settings (configuration options).

These star cards help form sets:

absolute sets: *all, *all plus, *star, *rstar
relative set classes: *self, *right, *type, *type plus right

And these represent settings:

help text: *add help, *edit help
permissions: *create, *read, *update, *delete, *comment
formatting: *structure, *default
pointers: *input type, *content options, *content option view
other: *accountable, *autoname, *captcha, *table of contents, *layout, *send, *thanks

Note that you can go to a set or setting card to see all rules associated with it.

Mail / Signup

These are used for flexible email and account-related emails.

email fields: *from, *to, *cc, *bcc
content fields: *subject, *message, *attach

The following configure signup communications, including email notifications and thank-you pages:

*invite, *signup, *request

Related Cards

Each card has a "related" tab entirely configured through cards:

subtab list: *related See how to customize Related subtabs.
subtabs: *incoming, *outgoing, *plusses, *community, *account
reference searches: *links, *linkers, *inclusions, *includers, *refers to, *referred to by, *tagged
plus searches: *plus cards, *plus parts
user searches: *editing, *editors, *creator, *created, *watching, *watchers

Other

These cards are simple single card config options:

basic: *title, *home, *logo
look and feel: *css, *favicon, *sidebar
advanced: *tinyMCE, *google analytics key

These cards are included in the Classic Layout and have autogenerated content.

*head — required, goes in HTML head
*navbox — the navbox
*account_links — links to current user's card, sign in/out, and signup
*version — current Wagn release
*alert — where notifications show up, defaults to bottom-right corner
*foot — required, goes just before /body on page's HTML

These cards offer metadata about any card when plussed to them (eg Home+*when created)

*when created - creation date
*when last edited - edit date
*count — the number of cards in a collection (Pointer or Search).

These cards configure valuable searches:

*account — existing accounts and Sign up
*recent — used for Recent Changes — all cards by update, inserts Date headers
*search — similar to a form, used for navbox results
