How do you see community-specific announcements and megathreads?

Community-specific announcements and megathreads are surfaced through two main mechanisms: pinned posts (sticky posts) and the community's post feed itself, with some moderation choices affecting how prominently they are displayed. Pinned posts appear at the very top of a community's post feed regardless of their vote score or age, overriding the normal sort order. A community can have up to two pinned posts simultaneously (or three under certain older configurations), and moderators use these slots for their most important ongoing resources: rules announcements, megathreads consolidating discussion of a major event, weekly or daily discussion threads, and community-wide reminders. When you visit a community, pinned posts are the first content you see, making them impossible to miss if you visit the community directly rather than viewing its content through your home feed. According to r/AskModerators discussions on megathread importance, megathreads consolidate discussion of a specific event or topic into a single thread to prevent the community's feed from being overwhelmed with similar posts. A megathread is a regular post that has been pinned and designated as the official discussion space for a topic. Users are directed to comment within the megathread rather than creating new posts, which keeps the feed organized during high-traffic events. One caveat noted in r/AskModerators discussions is that Reddit's algorithm does not give megathreads preferential treatment in users' home feeds — a pinned megathread will appear at the top of the community's own page, but it may not surface prominently in your home feed. To reliably see megathreads, you need to visit the community directly rather than passively relying on your feed. Bookmarking communities that regularly run important megathread events, or checking community pages directly during known events, is the most reliable way to engage with this type of content.
