Instant messaging and email are great ways to quickly get ideas and notices across quickly to co-workers, but sometimes an actual, real-time chat session can save you time on replies and confusion. ChatMaker, a free web chat application, instantly creates online chat rooms after you type in the name for one. Inviting others into the chat is as simple as sending them a human-readable URL, and nobody has to sign up or answer an invitation email.

ChatMaker is a free web service, no sign-up required. For more group chat options, check out Google Talk and the (very) similar ChatCreator.
