Generally, the Outdoor planner has not been as popular as the VisualRF Plan webby as fewer partners do outdoor RF; as such I do one quarterly. The next Outdoor Planner webby will be in November (the Oct schedule just went out).
The link maverick sent out is an excelent video and summarizes the tool really well. I cover much of the same content but go into a little more detail as I spend about 45 minutes showing the basics of creating a multi-node mesh network plus client access.
