Strunk’s Style
William Strunk's Elements of Style is available online. It's not long and has some advice worth digesting.
Unfortunately it advises:
Write to-day, to-night, to-morrow (but not together) with hyphen.
Write any one, every one, some one, some time (except the sense of formerly) as two words.
I guess, like The Homework Machine, it's not as perfect
As I thought it would be.
