Where are you guys storing your important files at? Having them only on computer can be a bad idea in case your PC crashes, then you can lose all your important stuff...
I'm using DropBox where you get 2GB of free space on the internet and you can even install a small app on all your computers, that makes the files accessible on all your computers. File sharing with others is also possible and some other great things...
I was using some other websites for storing my files but for now I like dropbox the most.
