Thanks for these tips. I especially like the suggestion about the metadata. I never thought of doing that.
There are reasons we can't do some of these but most of them are great to know! :) I don't put my TOU in txt format any more because I had a problem with people changing the wording.
With my commercial use stuff, I have it in secured pdf format now so it's concrete! :)
We also can't put our blog addresses in our TOU because of terms in our contract. So, I just include my email address and gds. Hopefully that's getting the job done!
I also include my full name in all of my file names because I've seen too many pirated files and orphaned files that have initials and no one can tell who they belong to.
