Welcome to Fluther. I see that at least two other people before me have marked this as a Great Question, and I agree. So if you don’t mind – which is just a figure of speech, after all, because it doesn’t matter whether you do or not – I’m going to follow the thread and see if I can learn any pointers, because I’ve been wondering the same thing. And I’m told that it’s never too late to learn a new skill, so let’s see what comes of this question. I sure don’t have an answer for you, though.
