What country do you live in? In Germany, you cannot give up your copyright. (It actually makes a finer distinction between creator's rights and copyright, and you cannot give up creator's rights - simply because you _are_ the creator of your work, giving that fact up would be like denying reality... ;) Pascal -- My website: http://p-cos.net Common Lisp Document Repository: http://cdr.eurolisp.org Closer to MOP & ContextL: http://common-lisp.net/project/closer/

What happens if a US citizen creates a virus and releases it to the public domain. Is (s)he responsible for the possibly large damage arising? Nicolas

And RG writes: > Which countries are those exactly? Germany (and much of the EU, iirc) has the idea of "moral rights" or "author's rights" that cannot be transferred. Those alter the definition of public domain. That's one reason why the Creative Commons folks came up with their CC0 license. http://creativecommons.org/publicdomain/ I haven't seen problems with public domain works like SQLite, and you're under the US jurisdiction that recognizes them (iirc), so it's a rather tempestual teapot.
