Do NOT apologize as there’s no need to. First and foremost, that’s what this forum is for (not just this thread, but the whole FlyerTalk forum). I realize a certain poster who has their own reputation for being a bit of jerk around here gave you grief (I came across that thread) but posters like that forget that there was a time they didn’t know as much as they do now. On top of that, the FT search function sucks. It’s actually often easier to find an FT thread via Google search than FT’s own search function, though if using Google to answer a generic question obviously using Google may lead to several other sites and results so that doesn’t always work. Also, any time you ask a question and post a thread, it allows other members to see the question - a question they may have had themselves or even something they didn’t even think or know to ask but now have gained the knowledge through the answer to your question.
