#### Content Rating

AlliMeta follows the Entertainment Software Rating Board (ESRB) content rating system used in North America to provide guidance for all content. The content rating will:

* Alert users that the gateway may contain objectionable content.
* Block or filter content for specific users in certain regions or as needed.

The content rating includes the following five levels:

* "Early Childhood" (EC) - suitable for children ages 3 and up.
* "Everyone" (E) - suitable for all ages.
* "Everyone 10+" (E10+) - suitable for ages 10 and up.
* "Teen" (T) - suitable for ages 13 and up.
* "Mature" (M) - suitable for ages 17 and up.

For more information about the content rating, please refer to the [ESRB official page](https://www.esrb.org/).

#### Gateway Type&#x20;

There are four types of gateways:

* Indoor: Set up this gateway so avatars can enter indoor spaces.
* Land #: Redirect to another land ID.
* Metaverse: Can be teleported to other metaverses.
* Website: Link to other Web2 websites.

#### Privacy Settings&#x20;

There are three types of privacy settings:

* Open: Set this gateway to public, so every player can interact with/enter it.
* Close: Close the gateway, preventing every player from interacting with/entering it.
* Verify: Limit specific players who can interact with/enter the gateway (whitelist, email, password...).

### Setting up 3D Billboards&#x20;

Each building NFT can have up to five billboard advertisements. When the building NFT has a billboard feature, you can set the image for each billboard at "3D Billboard". Users can post their 3D map layer land advertisements using a [third-party image library](https://imgur.com/). The process is as follows:

* Place the building NFT with the billboard feature.
* Click "3D Billboard".
* Copy and paste the image URL, then click "Save billboard".
* Interact with the contract and click "Sign".
