Similar to Brent's comments, I'd recommend starting the topic on Am.com and in the right forum category.
Step 1: Look at thread and elicit the most important points - sometimes a poorly framed question or topic, elicits poor responses. So, can you revise, or clarify the key questions at all?
Step 2: Summarize the responses you've seen so far, and why they are not on target.
Step 3: Re-state your question, and add specific questions you want answered.
When people are busy, pre-digesting the information for them, will usually help get you better responses.
Hope that helps...
BTW, what's the topic?
