Bryan, I use the discussion board for such these details. I actually tell my online students NOT to email me. I know it seems weird, but I've reduced my email overload drastically. So, students must post their question on the FAQ discussion board. They get extra credit for answering each other's questions. I monitor, but the students are good about answering each other and they will say things like "look it up in the syllabus - it's on page 5!" ;-) When students email me, I simply say, "Please post this on the discussion board so that everyone may benefit from the answer." They learn quickly.
