In the last few months I've learned a ton about using JOSM, making it super easy and fun to make big changes on OSM quickly. Learning a handful of not-so-obvious tricks, plugins, and shortcuts has made it easy for me to do lots of fast and accurate mapping in the St. Pete area.
Come hang out for a few hours and learn a bunch of cool tips and tricks for using the most-powerful (but also most complicated!) OpenStreetMap editor!
We can also just throw around any questions and ideas about OSM, and maybe even walk around town and do some real-world mapping on the street.
(The time and location are also up for change if anyone really wants to come but can't make it, just suggest any time and place that might work better and we can tweak.)
