Speaking of Latin (and I probably won’t even again – this is a one-shot subject) there is (for geeks around the world) a great site, named Lorem Ipsum, which allows you to generate pre-determined sizes of dummy latin texts – this allows you, for example, to fill a webpage with text for testing purposes.
