I was one of the first to vote in the poll, but debated on adding a reply until now.

I can only describe the way I'm doing the copyrights, I can't influence how other people do them..

Most copyrights are displayed only on pages produced by the add-on/mod.

Exceptions to that would be if a standard vB page has been heavily modified to display content that wouldn't normally be displayed (IE: the modifcation system). Then the copyright would also be displayed on forumdisplay and showthread pages.

I do not display a copyright if all a mod does is add information to the 'What's Going On' portion of the main page (IE: Style Statistics or Forum Home Statistics).

Neither do I display a copyright if on the surface there are only minor differences between a standard vB page and the same page with my mod (IE: Thread Status System).

So I guess it boils down to what the mod does. If it's relatively minor, there's no copyright. If it adds major pages or changes pages in a major way, then there is a copyright on those pages.
