# Groups

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.
* **Communicating with People**
  * Group Posts
  * Emailing
  * Texting (SMS)
  * Voice Calling

Read more about the communication methods in the sub-sections.
