@oristarA,
Well, when i get up in the morning (usually very early), there are dozens of new threads and thousands of new posts. It's easy to miss them, and most people posting here are probably on a daily schedule of GMT -5 hours, -6 hours, -7 hours or -8 hours (i.e., eastern time zone, central time zone, mountain time zone, Pacific time zone). So, when it's ten o'clock in the morning in London, it's 5:00 a.m. in New York, 4:00 a.m. in Chicago, 3:00 a.m. in Denver and 2:00 a.m. in Los Angeles.
Of course, it's not just Americans and Canadians who respond. But they make up the majority here. If you post a thread which does not get a response, and you have the opportunity, figure out what time it is in the United States and Canada, and come post "bump." That's known as "bumping up a thread" to bring it to the attention of other members.
