It’s always nice to look at a document that’s just been proofread and see no changes marked. It’s a bit less nice to hear the proofreader say that they marked several changes, but for some reason you can’t see them.
Today I was trying out a new way of working with proofreaders: Google Drive. Normally I just use Libre Office Writer or PDF editing software, whether I’m hiring a proofreader or being hired as a proofreader myself. But this kind of collaborative working is what Drive was designed for, right?
