Ask your questions in Pink Petro rather than through email. Not only will you be helping everyone by establishing the answer in a way that other people can use it, you'll be helping the person with the answer by limiting the number of times they answer it.
Plus, you'll receive a more thorough answer by engaging the community rather than a few select individuals.
When you mark a discussion as a question you're giving people even more incentive to answer. Once they do you can mark their answers as correct or helpful -- you'll give their reputation a boost.
