I know it's possible. What I had stated above though is I don't believe that any other page other than the parent of the child window that is opened displaying the graemlins can be accessed by the child window to dynamicly add the code. Each page, newpost, newreply and what ever else would need a link to open a related child window to be used for that page only.
I could be wrong as it has been a while since I have done much javascripting but if I do recall correctly the communication between pages is only possible between the parent and child windows. Opening page 1's child window will not allow that child window to access page 2.
Does your invisionboard allow for the addition of the graemlins to any page with just one child window or do you have to open the window for each new page? As I said it's been a while so I could be completely wrong. LoL
