APTA Communities will be unavailable beginning December 16, 3 pm ET, until as late as December 20, 5 pm ET, as APTA makes upgrades to the collaboration platform.

As a result of the upgrade, APTA Communities will have a familiar yet improved look and feel, with more detailed navigation menus and breadcrumbs and a "ribbon" menu for more intuitive content authoring and management.

APTA Communities allow groups to collaborate based on shared interests or responsibilities through discussion forums, document sharing, and more.
