# Groups

Groups are a special and import part of Lightpost for organization and communication.

Groups in Lightpost are centered around two primary functions:

* **Grouping People**
  * The ability to filter reports to specific groups.
  * The ability to filter the People section in the Admin.
  * Group rosters for taking attendance.
* **Communicating with People**
  * Group Posts
  * Group Forums
  * Group Events
  * Group Video Calls
  * Group ETAs
  * Emailing
  * Texting (SMS and MMS)
  * Voice Calling

Read more about group settings and each communication method in the sub-sections.

Who can administer a group, moderate its posts, and send its emails, texts, and voice calls is set for each group with [Group Roles](/core-concepts/groups/group-roles.md).
