I'm gearing up for some hopefully serious mapping.
I've configured my Asus EeePC to use an USB bluetooth dongle, and connected a GPS receiver to it. I have set up gpsbabel to record and convert my tracks and I will be driving around the city mapping the streets as much as I can in the next few months.
Early today I uploaded my first "test" trace which is just a stationary GPS track received by sticking out the GPS receiver through my office's window. I will be making my first true drive later today.
I'm also looking forward to getting more acquainted with JOSM.
