I know it can feel discouraging when you feel your questions or posts seem to be ignored. Usually that's not the case, more one of things getting lost amongst all the other hundred or so posts a day. Where possible I try not to let a post go unanswered but sometimes plenty of no or low reply posts slip through. The trick is to keep trying if you've heard nothing after a day or so, someone who can answer will connect with you at some point. I'm glad you're staying around
