# Thread Features

Threads are the core unit of discussion. Beyond posting and replying, threads support several features that help organize and highlight content.

## Pinning

Moderators and admins can **pin** a thread to keep it at the top of a forum listing.

- Pinned threads show a pin icon and a highlight.
- A forum can have several pinned threads.
- To pin, open the thread actions menu and choose **Pin Thread**.

## Locking

Locking a thread stops new replies while keeping the existing content readable.

- Locked threads show a lock icon.
- Anyone can still read a locked thread, but the reply box is disabled.
- Moderators and admins lock and unlock from the thread actions menu.
- A lock reason is optional but recommended.

## Best Answer

In forums set up for questions and answers, the thread author or a moderator can mark a reply as the **Best Answer**.

- The best answer is highlighted with a green checkmark and pinned to the top of the replies.
- A "Solved" badge appears on the thread in listings.
- The author of the best answer gets recognition and a "helpful" stat.

To mark a best answer, click the checkmark on the reply you want.

## Staff Pick

Moderators can mark a thread as a **Staff Pick** to recommend it.

- Staff-picked threads show a star badge and appear in the Staff Picks widget.
- The thread's author earns 100 credits when their thread is staff-picked.
- This is separate from pinning — a staff pick is a recommendation, not a positional override.

## Crossposting

You can crosspost a thread to another forum.

1. Open the thread actions menu and choose **Crosspost**.
2. Pick a destination forum.
3. A copy of the thread is created there, with an "Originally posted in [Original Forum]" note.

Each crosspost is its own thread in the destination forum. Replies are not shared between the original and the copy.

## Sponsoring a Thread

If your community has credits enabled, a thread author can **sponsor** a thread for extra visibility.

- Sponsored threads appear in a highlighted section at the top of forum listings.
- Sponsoring spends credits, and you choose how many hours the sponsorship runs.

## Bumping

You can **bump** a quiet thread back to the top of its forum.

- Bumping spends credits.
- It moves the thread up in the listing.

## Cover Images

Threads can have an optional cover image shown as a banner at the top.

- When composing, choose **Add Cover Image** and upload one.
- The cover also appears as a thumbnail in thread listings on desktop.
- Recommended size: 1200 x 400 pixels.
