if you mean cutting them from a word processor like MS Word and pasting them into the web-based secondaries (i.e.-Jefferson, CWRU, Dartmouth), then yes, that's exactly what I'm doing. No need to retype them - just cut and paste away.
Now if you mean typing them out, printing them, physically cutting the essays from the printed page with a pair of scissors and pasting them to your computer screen with, say, Elmer's glue....then sortof. I'm only doing that with Duke's secondary, and only after eating a lot of the glue.
