OK, I moved my copy of account.tpl to the /themes/default-bootstrap/modules/trackingfront, cleared the cache under BO->Performance, refreshed the page and didn't get my new account.tpl.
I have changed the text "Affiliation Space" at the top to be "BRGF Affiliation Space" and I also added a paragraph with text to the template. So it should be very obvious when my account.tpl kicks in.
