I apologise if this hs been written before - I did a quick search 
and couldn't find anything.

We all know that you cannot aperate into Hogwarts.  But, it seems 
that there is no trouble using the Floo network to go in and out of 
Hogwarts.  ...if their heads can be in another fire, then why not 
their entire body?

Wouldn't this be a very easy way to break into Hogwarts?

Any theories???
