There are people here to help, but you've got to try to start helping yourself. I don't mean to sound harsh, but you'll never learn if you don't actively do some research yourself. Don't just post here and expect everyone else to do the work for you. Try doing a web search first. Read up on what you want to know about. Then if you can't find anything, you need help understanding what you have read, or you want confirmation, THEN come here and post. Just put forth a little more effort, it'll go a long way!
