I must thank Erna for turning me on to WriteRoom. What an awesome thing it is! Nothing but an old-fashioned black screen with green terminal-style type. Hahaha! This is liberating. But it's got automatic spellcheck? What on earth. Is that red underline a good thing? I don't know, yet. We shall see...
Okay, that red underline can be turned off. WriteRoom is truly the distracted writer's dream come true.
