These are NOT rules, not sure why anyone thinks that. They are SUGGESTIONS for new hosts that ignore them anyway, then screw their clients with the sudden shutdowns. You want to look professional, then take the advice of a person who has been around for 10 yrs. Don't want to, fine, I really could care less as it's only that person that will look like a ---- when they shut down.
Of course if you bothered to look at the post below the one you decided to quote and then make the wiseass comment, you would have realized that your post is just ridiculous.
