"EMAIL" or "E-MAIL"
The "
Merriam-Webster Dictionary", "Gregg Reference Manual", "Wired Style" and the "Microsoft Manual of Style" prefers "e-mail" (with a hyphen and small "e"). So should you.
"ONLINE" or "ON-LINE"
The "
Merriam-Webster Dictionary", "Gregg Reference Manual", "Wired Style", the "Microsoft Manual of Style" and the "Chicago Manual of Style" prefers "online" without a hyphen. So should you.
"WEBSITE" or "WEB SITE"
"
Merriam-Webster Dictionary", "Gregg Reference Manual", "Wired Style", the "Microsoft Manual of Style" and the "Chicago Manual of Style" prefers "Web site" (two words and capital "W"). But the editors also believe "website" is acceptable for informal writing and predict that they will eventually accept "website" for formal writing as well. "
Wikipedia" and "
Dictionary.com" has no preference. So choose one! :)
