An activity is a way for you to organize your work and collaborate with others in a shared web space. You can start an activity from a single idea or fragment of an idea in an email. Because it is easy to invite new members, you can quickly pull together the people and resources you need to get the job done. You can post messages, share files and links to websites, and create and assign to-do items.
You can also create community activities. A community activity is an activity created in the Communities application. Community activities are included in the standard Activities views and can be opened and edited from the Activities application. The only thing different about a community activity is its membership. You can create a community activity with a membership list that reflects the membership list of the community or you can choose to create a community activity whose members are a subset of the community. But, the member list of the activity cannot contain anyone who is not also a member of the owning community. In addition, the public status of a community activity is determined by the community to which it belongs. If the community is public or moderated, all of its associated activities are public. If the community is private, all of its associated activities are private.
Note: See Creating community activities in the Communities API section of the product documentation for more details.
