In the back end there are various drop down menus eg "extensions" and under content "global content blocks"; some boxes say "add in the page specific meta data" and there are boxes where you can insert code - it may be that I haven't put it in the right quote marks, or exactly in the right place as when I tried the other night it came out on the home page when I viewed the site. There are only a few obvious places it can go but yes, you should be able to cut and paste the analytics code and drop it in somewhere into one of the boxes in the back end - if only I could figure out which one! As I say tried all the obvious ones, but only ended up with it making a mess of the home page so had to strip it all out.
I am moving to a new website on my .co.uk but would like to keep this site and turn it into educational papers, frustrating that I can't load the analytics on my own website, as it's such a basic!
