The main reason for a post not getting an answer right away is simply because the folks who have read the post do not have an answer for the questions asked. No one is being purposefully shunned, as some seem to think. If I don't have an answer, I just don't post to say I don't have an answer. And I miss alot of posts because of the fast pace of things. Bumping it back to the top doesn't make me have an answer, even if it is an emergency.
A couple weeks ago, one of mine went unanswered. No biggie. Happens on occasion. Doesn't mean anything.
