Today we are making collaboration on Smartsheet even better by introducing the Contributor seat: a new seat type that adds free commenting and the ability to include attachments on all user model plans at no additional cost.
The Contributor seat replaces the previous Viewer seat type. Smartsheet users will be transitioned over to this new seat type automatically and at no additional cost starting this week. This update will not cause any disruption to user workflows, and does not require System Admin action.
For customers using Smartsheet APIs, this change will be transparent and backward compatible. Also, please note that there is no change to the “viewer” permission on sheets, reports, or dashboards. Learn More.
