You could possibly make some screen shots and post them here. Also you could share your route (but not the map I am afraid).
To share the pictures (screen shots) you could use free web service like http://www.flickr.com
You will have to register and then upload your pictures. Later, in the forums click "Img" (while writing post) and insert the image_url from flickr.
To share some other files, storage on a server would be required [/img]
