If you have access to a remote workgroup, then provided that the remote workgroup has one or more projects and given that you have sufficient access to those projects, OfficeTalk will let you view those remote projects from within Project mode.
To do this, firstly drop down the list of projects. The name of the remote workgroup will appear after all the local projects. Select the remote workgroup. The drop down list will close and OfficeTalk will attempt to open the remote workgroup database. When this is done, drop down the list of projects again. This time, the list of local projects will have been replaced with projects belonging to the remote workgroup. Selecting one of the projects will display its tasks in the Task List window.
