Hi, all. I am Keith in Orlando (FL), and I have been using Visio on and off ever since Version 4, before it was owned by Microsoft (I think). I mainly use it for process mapping, but have used it for network diagrams, flowcharts, object-relationship models, database models, org charts, and sequence diagrams. I'm currently using Visio 2013's BPMN functionality to map out processes for utility and government software.
