Style Guide

Direct quote from the Associated Press Stylebook:
"AP style is email (changed from e-mail), but other e- words are hyphenated: e-commerce and e-book. Our amended style is website (one word, lowercase w), along with other compounds: webcam, webcast, webmaster. The Web is capped as a short form of World Wide Web, as are Web page, Web feed."

AP Style says its offline and online, but on-site and off-site.

Google Groups, not GoogleGroups

Yahoo Groups, not YahooGroups

World Wide Web on first reference - then just the Web.

Never substitute web with Internet; the web is part of the Internet, but the terms cannot be used interchangeably.
