# Communities

> Branded member spaces where you join, participate, and earn

A community is the top-level space you join. Each community is run by an organisation, has its own branding and rules, and contains its own challenges, rewards, posts, and leaderboards.

## Joining a community

Depending on how the community is configured, you may:

* **Join instantly** — open communities accept anyone.
* **Request to join** — an admin approves you before you get in.
* **Enter an access code** — invite codes can be single-use, time-bound, or limited by uses.
* **Enter a password** — community-wide password gate.
* **Confirm you meet age or custom-field requirements** — some communities collect additional profile data (email, phone, postcode, etc.) on join.

<Note>
  **Community rules acceptance.** Some communities require you to tick a checkbox accepting their rules before you can participate. If rules change, you'll be prompted again on your next visit.

## Navigating a community

The community page is your home inside a community. Depending on configuration, it may include:

* A banner with community branding, logo, social links, and a call-to-action.
* An **info modal / Learn More** — tap the info icon to see the full community description and rules.
* Cards for active challenges, achievements, rewards, and posts.
* A floating navigation button (FOB) or bottom nav with quick access to challenges, wallet, games, streak, leaderboard, shop, and referrals.
* Optional custom tabs configured by the admin (linking to external pages or embedded content).

The exact layout is controlled by the community's layout version — some communities use a vertical variant, others use the default horizontal layout.

## Posts

Communities can publish posts (text + media) that appear in-feed. You can like and comment on posts. Some posts require you to be signed in — anonymous users are prompted to sign in when they tap like or comment. See [Posts](/user-guide/posts) for details.

## Member interaction

* **Suggested communities** help you discover more communities from the same organisation.
* **Sharing** — many surfaces support the native OS share sheet (on mobile) or a link-copy fallback (on desktop).

## Social links

The community banner may expose the brand's external links — website, Facebook, Instagram, X, YouTube, TikTok, Discord, WhatsApp, Telegram, WeChat, and others. The logo may deep-link to a brand URL if configured, otherwise it takes you to the community home.

## Access control

* **Anonymous / guest** users can browse most content but get a sign-in prompt when they attempt to like, comment, claim rewards, or open restricted surfaces. See [Anonymous accounts](/user-guide/anonymous-accounts).
* **Restricted communities** may hide content entirely until you join, request access, or meet age requirements.
