In large actions, affinity groups usually send spokespersons to a spokescouncil meeting, to communicate and coordinate the different groups' decisions and then bring the coordinated information or proposal back to their respective groups for their final discussion and approval. Affinity groups also serve as a source of support for their members and reinforce a sense of solidarity. They provide a solution to the sense of isolation or separation that can occur when individuals act alone. By including all participants in a circle of familiarity and acquaintance, the affinity group structure reduces the possibility of infiltration by outside agents or provocateurs. Roles Within the Affinity Group Take turns so that everyone gets a chance to try different roles.
Individuals can take on multiple roles, too.
The role of support in a direct action is crucial. Support people also accept the responsibility of being contacts to the outside once a member of the affinity group is arrested. During and after a mass action support members need to stay in touch with support people from other affinity groups, for information sharing and emotional support. Know where people who are arrested are likely to be taken. If people are planning to use the solidarity tactic of withholding their names, collect everyone's identification documents and store them in a safe place.
