One good way to get involved in the OpenStreetMap project is to upload GPS track logs. They are then added to the background of the editing map as little dots. These dots are the basis for the manually drawn lines. If you're having trouble uploading a file, this page and the FAQ might help.

File should be in the GPX format. The server understands standard GPX Version 1.0 and 1.1, except that the tag
The geographic datum of OpenStreetMap worldwide is WGS-84, so please make sure your uploaded tracks are in WGS-84 lat/lon. GPX files should always be in WGS-84, but you have to be careful if you convert your tracks from other formats (and possibly other datums) to GPX.
Files may also be uploaded after being compressed by gzip, having a .gpx.gz extension.
For more information on GPX and creating GPX files see Making GPX Tracks.

A list of your traces and their current status will be shown below the upload form.
With tagging, you can put your files into categories. Each file can have tags. Usually, tags are the country and the cities, that your trace concerns. You have to separate tags by spaces, not commas (,). If you have any comma in the tags field, the upload will fail! This also means, you have to use underscore (_) in tags instead of spaces!

Your GPX file is parsed by the OSM server and points are extracted. These are added to the background of the map seen when editing.
There is also an option to delete your file.
