I'm using the WTFPL in my personal projects published on GitHub.

Currently I'm using it verbatim, but I have the suspicion I shouldn't be leaving

Copyright (C) 2004 Sam Hocevar <[email protected]> 

in there, and instead should use my name.

But the license is very confusing about this. Half of the WTFPL is about the WTFPL itself, so I thought that copyright might refer to a copyright on the license text itself, and not on the project this is licensing. Also, it says

Everyone is permitted to copy and distribute verbatim or modified copies of this license document, and changing it is allowed as long as the name is changed.

So would I have to change the name, from WTFPL to, say, "WTFPL-Domenic"?
