Also from the Canadian Style Guide (1997):

7.04 Imperatives, exclamations and indirect questions

Use a period after a mild imperative or exclamation:

If you want to know who is going to change this country, go home and look in the mirror.
-- Maude Barlow

U-turn if you want to. The lady's not for turning.
-- Margaret Thatcher

From the very witty Canadian Style Guide (1997):

2.03 Nouns with adjectives and participles

a) Hyphenate noun-plus-adjective compounds (in that order), whether used attributively or predicatively:

duty-free goods
tax-exempt bond

b) Hyphenate noun-plus-participle compounds regardless of position:

snow-capped mountains
a time-consuming activity

Exceptions

There are a number of them, including handmade and handwritten.
