Forums have 'off' times, times when the people who may take an interest in your post are off at work, sleeping or hanging with their friends. And has already pointed out, it's a busy time for the forums. Don't take it personal Alex. Some people are just lurkers or don't feel they have anything constructive to say. Again, don't take it personal. People are just busy.
Edit: Yeah, I know how those kind of days go.
