I just came across this board. Great idea. This is my structure that I've been dropping things into. I give each file a basic name that describes roughly what the viewer should think about when they read it.
In the PleaseRead.txt file:
>You did not find this USB flash drive by accident.
>I left it here, just for you, though I do not know what your name is, what you look like, where you work, or what you believe.
>You are welcome to erase everything on this drive and use it for your own purposes, but before you do, allow yourself to consider the following:
>Nothing on this USB is able to cause damage to your computer. I know it's a tall order in this day to take a statement like that on faith.
>However, despite the above, every document on this USB is able to call into question most of the preconceptions you have been raised to coddle your mind with.
>The choice is yours. Sift through this information, and decide whether you will share it, or wipe it. It's as simple as putting it back where you found it.
I haven't dropped it anywhere yet, and I'm still gathering material. Use the message. Great board, great idea.
