Unfortunately that computer crashed and I lost all my bookmarks. What was nice was that one could simply upload 2 coordinate files and the server returned the superposed coordinates that could be downloaded. I would be grateful if someone could tell me the URL for this nice automagic superposition server. Thanks in advance, Fred.
