Abstract: Medium, method and system for ad hoc, ambient, synchronous multimedia collaboration in a group-based communication system. Embodiments of the invention provide a way for users to quickly establish a real-time collaboration among a group of peers without the burden and overhead of a conventional call or video meeting. Users can quickly and easily join and leave these synchronous multimedia collaboration sessions at any time, without disrupting the session for other users. This enables the user to experience the collaboration as a convenient forum rather than a burdensome scheduled event.

Abstract: Media, methods, and systems are disclosed for ad hoc, ambient, synchronous multimedia collaboration in a group-based communication system. Embodiments of the invention provide a way for users to quickly discover and initiate real-time collaboration sessions among groups of other users without the burden and overhead of a conventional call or video meeting. Users can quickly and easily discover and switch into and out of these synchronous multimedia collaboration sessions at any time, without disrupting the sessions for other participating users. This enables a diverse set of users to experience a rich multimedia collaboration session collaboration as a convenient ad hoc forum rather than a burdensome scheduled event.

Abstract: Medium, method and system for ad hoc, ambient, synchronous multimedia collaboration in a group-based communication system. Embodiments of the invention provide a way for users to quickly and start a real-time collaboration among a group of peers without the burden and overhead of a conventional call or video meeting. Users can quickly and easily join and leave these synchronous multimedia collaboration sessions at any time, without disrupting the session for other users. This enables the user to experience the collaboration as a convenient forum rather than a burdensome scheduled event.

Abstract: A multiple user advertisement account system includes an advertisement account database for storing information related to the account. The system is configured to grant multiple users access to the account and allow the users to view or update the information stored in the account database. The system tracks the updates to the information and generates a display of an activity log that contains entries related to the updates received.

Abstract: A method of providing an advertisement including receiving a request for an advertisement of an advertiser, determining a purchase history for a user associated with the request for the advertisement, providing an advertisement of an advertiser in response to the request for the advertisement, and generating an advertising fee to be paid by the advertiser based on the purchase history of the user.

Abstract: An ad placement system provides functionality for users to rate advertisers associated with particular ads they view, and/or to rate particular ads. The ratings supplied by individual users in association with a given advertiser are used by the system to generate an average or other aggregate rating for the advertiser. This aggregate rating is exposed to users in association with the advertiser's ad or ads, allowing users to efficiently take the advertiser's reputation into consideration in deciding whether to click through or otherwise select such ads to access the advertiser's web page or site. For example, in one embodiment, each ad is displayed with a corresponding visual indication of the aggregate rating of the advertiser.

Abstract: An ad server system takes into consideration information about a user who clicks on an ad in determining whether to charge the advertiser for the click event, and/or in determining an amount to charge the advertiser. In one embodiment, unless the user is recognized, the advertiser is not charged for the ad selection event. Thus, advertisers do not have to pay the ad placement provider when the users who click on their ads are not recognized. If the user is recognized, the ad server system may determine whether and/or how much to charge the advertiser based on information about the recognized user. This information may include, for example, whether the user has set up an account, whether a valid credit card is on file for the user, and/or other types of user information that can be used to hold fraudulent users accountable for their actions.
