Yuku free message boards

In an effort to access Community Statistics privately (instead of having them show on the forum), I have signed up for Statcounter. I may be wrong, but I think that might allow me to do want, but how to get it to work is another story.

I registered with them and then I emailed them an asked how to enter the code, and this was their response:
"Does your Yuku Forum have header/footer file under templates folder? If yes simply paste our code at extreme bottom of header/footer file and your statcounter will then start tracking your visitors."

I have no clue if Yuku has header/footer files nor do I know where the template folder is. Right now I am using the Horsing Around skin but am thinking of switching to Dancing Horses, but, of course, I do not know how to do that and not screw up all the activity that has gone on up till now.

If I were to forget about the statcounter, can I just change skins and all the data will mysteriously appear on the new skin?

Can anyone help this stupid moron?
Thanks!!!
