I'm just starting out in SF, and don't have a lot of development experience. We have a customer portal that was recently developed, and I need to tweak it a bit to output the current user's main account name in the header of the portal. As far as I can tell I can only upload a static HTML file via the Documents section of our instance. Is that correct? How would I pull in a dynamic value to that section of our portal?
