Hi Satauna, The only reason for submitting arc or kes files is that they can keep the images, which could be rescanned later as the technology improves. However, the files with images in them are *very* large, and most people find them cumbersome because of the slow uploading and downloading. So .rtf is the preferred format. So if a person isn't keeping the images, which most people don't do, it would be better to submit in .rtf. Hth, Kellie
