You have to realize that unanswered questions are part of being a member of any site such as this one. There are reasons for questions going unanswered.

1) Poor timing: people here come and go, and check on the site in their free time. 99.99% of the people here are here because they want to bee, not because of any obligation. Your question just might have gotten neglected because it was posted in off hours, it happens to all of us. If a reasonable time frame has passed and you still want it answered, try reposting it.
2) Was it something REALLY easily looked up in a manual or a really simple google search? If so, the members here tend to be polite and leave the question be. On other forums you would get flamed to the point of tears for asking something obvious, even if it isn't obvious to you. Once again, wait some time, try doing some research and post it again.
3) Wrong forum. Many times a question will go unanswered because it gets posted in the wrong forum. People might not know the answer and wait for someone else to come along to take care of it, but that person never sees the question. Once again, wait some time and repost.

Those are just some off the top of my head, you questions might not get answered for something totally different or any combination of the above. Point is, try again. You're not being neglected, you're just a part of a mass of traffic, be persistent.
