A couple of things:
1. First: people are here in their own free time. They are not obliged to reply, and even if they do, that may take time. I come here when I have the time. Sometimes a few times a day, sometimes it takes days. Screaming for attention is not the best way to make friends here.
2. Secondly, writing in ALL CAPS is considered SHOUTING which is ruder than not saying Hi if you ask me.
3. Finally, this is a tech forum. People come here to post, read and answer tech questions. It's not a general chat box, so people may tend to ignore posts like yours (I know I do). Just post a good technical question, and you'll be surprised by the answers you'll get.
