Personally i dont think people intend to ignore certain questions. The majority of us are only answering questions based off experience not knowledge. Therefore, if there is something that one of us hasn't encountered before and doesn't feel comfortable giving advice, then quite sometimes people wont leave a comment. This doesn't mean that its personal, it just means that we don't want to give false hope or false answers.
Like others have said, bump it up or search for a similar question and see if that user has had any better luck.
Also, through my own experience, I've found this forum is a fantastic support network and you can build some lovely friendships that can help you through whatever situation your going through. However, coming along and posting a post such as your own if generally going to make people stand offish. People on this forum want to help others and gain answers or advice for themselves. I personally love this site and the people on here are fantastic. Please respect that and ask questions in a pleasant manner. There are a lot of us here that would be more then interested to know what your question was that didnt get an answer.
