 For **tells**, the game provides the sender’s content ID and world, so invites work reliably. For **FC, LS, and CWLS**, the plugin uses the sender’s content ID when available (e.g. from the last message in CWLS), so cross-world invites work for CWLS and same-world for FC/LS.
 
+### Auto-accept party invites
+
+When enabled, the plugin detects incoming party invites and automatically accepts them if the inviter is on your friend list or is a member of your Free Company. You can toggle friends and FC members independently. The friend list and FC roster must have been opened in-game at least once for the plugin to recognize members.
