How To View Unread Posts and Replies
SMF has several options for users to view unread posts. Unread posts are topics and replies that have not been viewed by the user. The most common way to view unread posts is through the links in the userbox near the top of the forum.
- Show unread replies since last visit – Selecting this option displays a list of the topics which have had new posts made in them since the user's last visit. The user has the ability to select to view all unread topics which will display any topic with unread posts, regardless of their last visit.
- Show unread replies to your posts – Selecting this option displays a list of topics the user has participated in that have unread replies.
Users may also choose to view unread posts outside of the userbox.
