ah! this "issue" has come up in a group project. 2 of us are from the law school (where it just depends on who you work for whether 1 or 2 spaces), and one is from main campus (we're all in a personal financial planning class), and she is used to 1 space.
I've decided that since I'm basically leading the project, we will use 2 spaces, so I'm going back through everything and adding spaces. sigh,
