Welcome to the Forums. The question you ask has already been covered MANY TIMES before. Just look/search around and you'll find lots of information.
I see you've been VERY busy in the short amount of time you've been here...Unfortunately I also see it's mostly spam posts or advertising your webpage.
I'm going to lock this thread down and I'm going to ask that you look around first and do some search and then if you still have questions please ask them with as much detail as you can.
There's plenty of people that want to help, but not so many that want to keep repeating themselves.
