About sharing
When you create maps with ArcGIS Explorer Online, you can save them to your content in ArcGIS Online. By default your maps are private, which means only you can access them. Similarly, when you add other types of content, it is private by default. However, you can choose to share one or more of your items with everyone who has access to ArcGIS Online, or with select groups of people. Once you've shared an item, it can be accessed by other users of Explorer Online, the ArcGIS Online website, ArcGIS for iOS, ArcGIS for Android, and ArcGIS Desktop.
Sharing is a way you can add value to your maps and data by sharing them beyond your existing colleagues or associations; you are encouraged to share maps and data if they are useful to others. For example, you might want to share a map that shows your local watershed system, or a utility network of your county.
Some maps or services are not appropriate to share publicly with everyone. For example, maps that are works in progress and proprietary or that convey business-sensitive data. With works in progress, you probably want to share the map only with a group that is involved with validating and fine-tuning the information. However, once the map is finalized, you could then share it with everybody (in other words, make it public). In the cases of proprietary and business-sensitive services and maps, you will probably always want them to be private. In other cases, the data contained in a map or service is available only within the network of your organization; if the services providing the underlying data are not accessible to the public, the item would not display correctly if an external user attempted to access it.
Using ArcGIS Explorer Online, you can share your maps. Once you have shared a map, you can provide direct links to the map or the presentation, so people can view it without having to search for and discover it. You can also share a service to allow others to easily find it and add it to their own maps.

Searching ArcGIS Online for maps
If your account is associated with an organization in ArcGIS Online, you may have the opportunity to share only with other members of your organization, with all users on ArcGIS Online, or both, depending on how your organization has been configured.
Maps and services can be shared with one or more specific groups, allowing members of the group to collaborate and share information about a specific topic.
You can also refer to the ArcGIS Online website help for more information about sharing maps.
