[ JDK VERSION : 1.6.0_07 ]
On Windows, user name is initially set from name of Window's current
user name. (LINUX etc.: I don't know)
IMO user name should be editable from Options->General dialogue.
It should overwrite templates user name, and maybe other values I'm
not aware about lacking deeper knowledge.
1) select Tools->Templates.
2) Expand User Configuration Properties, select User.properties and
open in editor.
3) Add e.g. "user=Mr. Unknown"
Additionally there also should be some project level user name, which
overrides it. There should be a reasonable relation to
application.vendor in project.properties.
Comment from Lukas Hasik:
"Uggh, that's ugly. ... IMO, it should be reflected in UI in better
way. Maybe a button "Change User Properties" in the Templates manager
or a special field in Options that would allow you to setup the user
reassigning to UI experts to decide what to do here. Then it can be implemented...

Martin, this is related to the other issue about user name in templates....
There's a "Settings" button now on the Template Manager, which opens the User.properties file. It's not a great usability improvement, but it's easier to find, at least.
It should be improved also by issue #221998 and issue #103851.
