You go to http://www.dropbox.com, register an account, can upload up to 16GB of files from your PC and then link anyone to them. It's fairly intuitive; you can probably figure out how it works within ten minutes or less. You will probably need to copy any files from your DVD-R on to your main hard drive before uploading, although you might be able to upload directly from the DVD-R itself (I have never tried this so cannot say). I suggest that everyone makes a dropbox.com account to support our burgeoning e-book trade. I'm going to upload more titles myself very soon. It's also good to have an on-line file cabinet to secure any files you'd like to back-up from potential loss. You may want to get as much as you can from your DVD-Rs on there anyway, as DVDs can be finicky and don't always have the longest shelf life.
