File manager

Hey Guys, so I've just become the admin manager of a new FTH webpage for the newly chartered club of Swinburne Toastmasters.
My question is two fold: how do I bring the file manager to the drop down menu at the home page?

and

I have a you tube video to pop in the custom web page, and it tells me it is an invalid URL. This video runs fine elsewhere. Any suggestions?

1) we require your club number to answer any questions
