I totally get the distinction between writer and author. I've written for others and for myself. It's a job and an art that I love to create. And don't feel too bad about mistakes, I'm still finding them in mine and I hate errors as much as anybody else. Even the edited manuscripts, I'm still finding errors. I think my writing program goes in and changes things like an evil little elf, just to mess with my brain. It wouldn't surprise me in the least.
