Hi,
I do not know for sure, and this might be an even bigger issue, if, for example, you use a program and take their "pre-sets" and then that person uses the same program and pre-sets.
I remember Front Page (still use it ... simpler to just type!!!!!) and it was nice to see all those frames, but navigating through them and setting them up was a huge arpthenic pain. I still don't use frames!!!! I might get someone to clean things up, but all in all, I just want it to be me, and I'm not the slick type to show off anyway!
This is the "internet" and everyone takes and grabs and steals something. I'm not sure that any "legal" solution is going to help, while also making it worse ... think of musicians using the same set of 10 notes and Big Shot Schmue suing for royalties! Or Petty Sam Boy! Or Marvin the Somebody! or worse, some rap this or other that uses guns instead of a legal system!
Careful what you ask for? I don't know ... I have had a screen play stolen, but it will never be used in my time ... and the bigger issue? They are not me! They will never make that film work. It will be a curse that they will regret to the end of time!
