I want to make sort of an e-card website that is different and more hi-tech than the others. But I have everything set up (pictures and other programming) except a few things.
I want to make it so that when you type in the window (*not* in a text box) or a frame, it writes on the screen (and stores the info in it's cache).
Once they push "Send", it (from cache) writes to a random named (for security reasons) text (.txt) internet file (but it finds and doesn't write over other text files, or else that people would lose their cards
).

Javascript or what can do this?
