Editors and proofreaders may be suprised to discover that there is an organisation devoted to their needs, namely the Society for Editors and Proofreaders. The society runs training courses, holds conferences and has a magazine called (rather cleverly) Editing Matters. It even includes a self-test in proofreading that you can run online to find out just how good you are at proofreading.
It’s also worth noting that Scrivener for Windows 1.0 has now been released. You can buy a copy from the Web site for just $40 or download a 30-day trial version for free, and I highly recommended it.
