Preparing launch of website

 Hello everyone,

I'm wondering how I can prepare the launch of my website : 

 

  • be sure that there will never be a page or message specific to ELGG (like 'technical error 56416851658' with a blue layout - but that's just one example)
  • dissociate the administration ? (admin does not login on the website but on another url unknown from the user?)
  • be sure that there is no possibility for a user to call install.php or some known elgg core files

This kind of things... (do you see anything else to be taken care of ?)

Thanks in advance.
