To expedite your request, don't be stingy with the details. Help us help you by telling us as much as you can, especially if you're having a problem. Browser information, user names, steps taken, and thorough descriptions of what did (or didn't) happen are things we're quite interested in.
One request is enough: sending multiple requests will not get you a faster answer. It will delay a response by placing your requests together at the end of the queue. You can update an open ticket with new information by checking on your request and adding a comment.
