Let people know that a post has expired and lock it down.
A Flarum extension. Mark posts as expired. An alternative to https://github.com/FriendsOfFlarum/prevent-necrobumping. Huge thanks to the Friends of Flarum group for the necrobumping extension. This uses their code and changes things up a bit so that there are no replies after so many days and the post is clearly marked as expired.
composer require zerosonesfun/expired-posts
composer update zerosonesfun/expired-posts
