>What are extra flags?
Extra Flags is an open-source and non-malicious plugin that adds regional flags, like states and provinces, to the already existing national flags on /int/, /pol/ and /sp/, by storing users' post number along with the selected regional flags, and retrieving it from a database when a thread is loaded. You can add your region's flag by requesting it on the GitHub page.
