In slightly surprising but welcomed news, the U.S. General Services Administration announced approved terms of service agreements for the collaboration service Slack.
From GSA:
The team communication platform, Slack, is a collaborative working area. The tool has an array of features – one-on-one messaging, private groups, persistent chat rooms, direct messaging – and is available as both an app and web platform. Users are able to search all of the content in a team’s Slack through one search box. This TOS agreement was negotiated by the Department of State.
Other newly-approved services include IFTTT, StackExchange and Trello.
