How to read this Site Association Index. The ID column lists the unique identifiers for each asssocation. The Tools column gives links to modules that work with the association (for example, finding other associations similar to it). Each association is contained in one Map; the color of the background stripe of the association in this table is determined by its map. Each association may have an Association Legend, and must have one Type, which may determine which of at least two Roles and Players plus Notations combinations a valid association must have. (A notation may be used to specify a helper application for a player whose text is in that notation.) Association types, roles, players, and notations may be represented by icons, names, or both icons and names. Associations, association types, association legends, roles, players, and notations are all topics. Each topic may, at administrator option, link to a topic page. When the Site Map is sorted on the Association column, redundant table cells are removed, and all the posts in which the association appears are consolidated into a single cell.
