https://xenforo.com/community/threads/maximum-mention-alerts.175333/#post-1398797 It's usergroup controlled, mostly to reduce notification spam (spambots can easily abuse mentions). We may eventually have to make a separate user group for Mafia just to avoid this limitation, but for the time being, we can increase the mentions limit to a decent amount or you can double post if needed. Maybe in the future we can have an advanced feature that allows you to mention all users that have replied to a thread, for Mafia only ofc, or just have it where you can fill out who the host is and the participants invovled in the game.
