DailyStrength is a division of Sharecare that serves as a social network centered on support groups, where users provide one another with emotional support by discussing their struggles and successes with each other.

The site contains online communities that deal with different medical conditions or life challenges.

As of November 4, 2007, DailyStrength has created over 500 support groups focused on issues such as depression, divorce, parenting, and a wide variety of cancers; Furthermore, health blogs, expert answers, treatment, and a non-professional community of support located all over the world.

An online community is a virtual community whose members interact with each other primarily via the Internet.

For many, online communities may feel like home, consisting of a "family of invisible friends".

Those who wish to be a part of an online community usually have to become a member via a specific site and necessarily need an internet connection.

An online community can act as an information system where members can post, comment on discussions, give advice or collaborate.

Commonly, people communicate through social networking sites, chat rooms, forums, e-mail lists and discussion boards.

People may also join online communities through video games, blogs and virtual worlds.

An Internet forum, or message board, is an online discussion site where people can hold conversations in the form of posted messages.

They differ from chat rooms in that messages are often longer than one line of text, and are at least temporarily archived.

Also, depending on the access level of a user or the forum set-up, a posted message might need to be approved by a moderator before it becomes visible.

Anonymity, adjective "anonymous", is derived from the Greek word ἀνωνυμία, anonymia, meaning "without a name" or "namelessness".

In colloquial use, "anonymous" is used to describe situations where the acting person's name is unknown.

Some writers have argued that namelessness, though technically correct, does not capture what is more centrally at stake in contexts of anonymity.

The important idea here is that a person be non-identifiable, unreachable, or untrackable.

Anonymity is seen as a technique, or a way of realizing, certain other values, such as privacy, or liberty.

In a support group, members provide each other with various types of help, usually nonprofessional and nonmaterial, for a particular shared, usually burdensome, characteristic.

Members with the same issues can come together for sharing coping strategies, to feel more empowered and for a sense of community.

The help may take the form of providing and evaluating relevant information, relating personal experiences, listening to and accepting others' experiences, providing sympathetic understanding and establishing social networks.

A support group may also work to inform the public or engage in advocacy.
