I'd say "Don't talk if you don't read the entire description" instead of "Don't talk if you got no clue about it."
What is the difference? They seem the same to me.
Don't talk if you got no clue about it. There are 2 packages, 200$ and 300$, with 300$ you can have a subdomain (aka dns, like no-ip.org). So you don't have to change the ip ever. He gives ya the no-ip account.
