Am I the copyright holder of my username (on any site not just this one.)?
If my logon name is an email address, do I own the copyright on the email address (assuming I own the domain)?
More importantly do I own the copyright on my actual password?
Why I ask this is because there is quite a bit of discussion/movement on privacy matters.
If I own the copyright on my username how can Google (or anyone else) sell or market my private information to third parties using my username or indeed my email address? Do they breach my copyright?
