garynamy, the only definition my American Heritage gives is "giving cause for legal action." I've never heard the term used to mean anything else (but, I work in the law, so my view may be skewed). It sounds to me like this use of "actionable" is brought to us by the same corporate-speak folks who brought us "incent." Good luck trying to kill it.

Let's help garynamy by giving him a pithy alternative.
