All files you create as part of your DW development work should have an appropriate header file. If you completely rewrite a file that used to be part of LiveJournal's "livejournal" repository, but no original code remains, you should indicate that as well (along with a link to LJ's license).
Right now, we don't have a header for code that was from the "livejournal" repo and has been modified by us -- you can just leave those blank.
Copyright is maintained by the Dreamwidth Studios, LLC. organization, as all committers/contributors should have signed a contributor's agreement to properly grant license to their work. But authors should be noted for credit purposes.
Rule of thumb: if you are writing a new file, you can add yourself to the authors. If you are editing an existing file, you should only add yourself to the authors list if you are making significant changes (>10% or 100 lines, whichever is less). (Fixing typos does not qualify one to be a called out author of a file, sorry!)
Exception: if you're splitting a file into two or more new files and deleting the original (eg, when converting a site page from BML to TT), keep the original authors and add yourself to the list for all new files, even if one of the new files ends up with more than 90% of the code that was in the original file.
Note: in both cases, author call-outs are just name and email address. Even for major changes, go to the repo if you want to know who did what.

Header for files that were livejournal code and have been partially rewritten/changed
Right now, these files don't have any header. (We haven't decided what the header should be.) If you edit one of those files, you can leave it without a header.
