flyzoo script

Hi guys,

Cant figure out where to place a flyzoo chat script into my elgg site.

the instructions say "Place this tag in your page right before the closing </body> tag or into the footer/master page of your site."

Ive tried inserting it surrounded by html tags but nothing is working,,, what is the equivalent to master page in Elgg, and how best to install this script?

any help much appreciated.
