  In "The Lost Prophecy" (pg. 830, American Edition), Dumbledore says 
to Harry:  "He [Snape], like you, attempted to contact Serius at 
once.  I should explain that members of the Order of the Phoenix have 
more reliable methods of communicating than the fire in Dolores 
Umbridge's office."

What does he mean by 'more reliable methods of communicating'?  And 
does this mean that the methods we know of (owls, floo powder, 
howlers, etc.) are UNreliable? 
Any thoughts?

REPLY:  
I am curious about this as well....perhaps, two way mirrors such as 
Sirius had, charmed two-way parchment, other charmed objects that 
allow communication iwth one person or a group of people...????

Either way, I am disappointed that none of these methods was passed 
along to Harry to be used to communicate with Sirius and even the 
Weaseleys with their parents.
