A "sticky" thread, sometimes called a "pinned" thread, is a post that stays at the top of a forum page, regardless of how old it is or how many new posts are made.  Benefits would include:

Prominent Information: Sticky threads are ideal for important announcements, rules, FAQs, or guidelines, ensuring everyone sees them when they visit the forum.  They reduce repetitive questions and help maintain order.

Consistency for New Users: Sticky threads often contain introductory or orientation content, which helps new users understand how to participate and use the forum effectively.

Centralised Updates: For ongoing events or updates (such as game patches, community news, or feature changes), sticky threads keep all relevant information in one accessible spot, minimizing the need for scattered posts.

Community Resources: Many forums use sticky threads to pin valuable resources, such as guides, popular links, or answer compilations, saving users time and allowing easy access to helpful content.

Increased Engagement on Important Topics: By keeping important discussions visible, sticky threads ensure they receive more attention, engagement, and contributions from the community, fostering a stronger sense of participation.

In short, sticky threads are a useful organisational tool, helping keep critical information at the forefront and making the forum more user-friendly for everyone.

I think it would be a great and important update to see on the forum.
