Whether or not you register your idea, a way to HELP insure your idea is protected while typing it on your computer, is to password protect your document. Or, the program. I use a external hard drive where I back up my work into, that way I don't have to worry about one of two things happening, one the computer crashes or two, God forbid my house gets robbed and they steal my computer. I use an I-book that I have concealed behind my desk as well as a flash drive for drafts that I update all the time.
