In case anyone is interested; a handy rule of thumb (i.e. it isn't always true, but will hold you in good stead) is that "which" should be preceded by a comma and "that" should not. If you write a sentence that requires the comma, then it's "which"; if it requires not having a comma, then it's "that". e.g. "git is a version control system, which is a piece of software used for tracking changes to files over time" "git is a version control system that has a fanatical following of users who will kill anyone who asks for rename support" In the first case the "which" describes what a version control system is. In the second, the "that" describes what git is. Andy -- Dr Andy Parkins, M Eng (hons), MIEE andyparkins@gmail.com
