This site is an example of configuration. If you don't know how to modify or what to add (And if you arrived here and why you don't know it!), You don't change it.
Use this site only as a starting point to change your web-site. It took me 2 hours to get it working again (bad!). I (like you) not know as edit this site and am trying to learn. I don't change anything. I don't change anything. I have respect for peoples want to learn. please don't mess it up !. (i'm sorry for my bad english)
