But if you select "download from OSM" and use the "find" tool (not the map window) to select a town you're interested in (preferably a small town!) then it'll go and download the data for you and show it on a black background. It's a powerful tool, with lots of options, and it's not particularly friendly when you start it for the first time. You should have at least java 1.5 installed already before you start. JOSM (Java OSM editor) is a standalone java application, rather than an in-browser tool, so it takes a bit more effort to get it going - but not much more than a download of the jar file. But once they are, they become available to everyone thanks to you! And even better, next time you make an extract from OSM for your GPS receiver, it'll have your edits in for you! JOSM In any case it does take some time (maybe a few days, maybe longer) for the changes to become "live" in openstreetmap maps. It can still crash the browser though so if you're doing anything more than a quick edit or two you may want to look at JOSM (see below) which provides a more robust tool for frequent edits. One tip is to zoom in tightly to the area you're interested in editing before you go into the edit mode, to reduce the amount of data which has to be downloaded. It also requires a bit of patience as the data gets downloaded and the tool can lock up occasionally, so make sure you save often. Accuracy is more important than speed, however. Once you've practiced, and got the hang of the tools, you can go to the real "Edit" mode and start editing the data for real. There is a bit of a learning curve, and it's not always intuitive to use, so make sure you practice using the "Play" mode before you make a mess of someone else's carefully-created data! Once that's done though, you can get started immediately with naming roads, adding points of interest and so on. You do need to register though, and you do need a valid email address for them to send your confirmation code.
You don't need to download any extra software, you just need to look for the "Edit" tab at the top of the map.
The easiest way to start is with the built-in editor in the openstreetmap website. The best place to start is their Beginners' Guide which outlines a few of the ways you can help. If you so wish, you can help the openstreetmap community build better maps by editing or otherwise contributing to their maps.
