Hi, sms2luv!
Posting at a thread without adding anything useful, just to bounce it up, doesn't guarantee better probabilities of getting answers to your original question.
I think that people who usually read these forums or who stumbled over your question, receive a very first impression after reading the original post: either they understand and can help or they understand and are not willing to help or they don't understand.
In any of the three situations I believe that no one will be more tempted to get involved in a thread just because the OP insists, and I repeat, without adding any useful information. Even more, I tend to think that they're less tempted to participate.
For your peace of mind I can assure you that there a a group of very well qualified members of Chandoo.org's community that regularly (I'd say daily) read every question posted at any forum. Surely not all of them all comments at every thread, but I'd bet on that many people read daily every post. If they don't participate, it's up to them. They may think that cannot help, they may not be interested in the subject, there are a lot of reasons why... remember that we all do it for free, in our free time, without any obligation.
Please notice that the sum of time available for collaborators has to be distributed between all the questions posted by the community. Sometimes it happens that there are members who abuse on posting/asking/demanding (I'm not saying in any way that could be one them), and that reduces significantly the medium time/dedication resulting for regular non-abusive members.
Please be patient, I recommend you to read this, if you haven't done it yet, which seems you haven't...

Where you may find this:
"
Consider that the world is operating 24hrs a day. A late post today may well be answered by someone else overnight."
And this:
"
If you and a reader have been involved in an ongoing conversation and the conversation suddenly stops, recognize that the person may have gone to bed, even though you have just arrived at work. In the worst case a reader may go on holidays and not get back to the question for a few days."
If that's not suitable for you, of course that you can always hire a consultant and agree with him the terms of the response time."
Personally the comments to bump up non answered threads move me farther away from reading them again. But this is not a general rule, it just happens to me.
Regards!
