JKR has answered the FAQ Poll. How doe the Order communicate? won. 
She expresses surprise at that and says the other two questions have 
such interesting answers! Now, what were those questions??? She also 
says they will be answered in book 6 which is, I think, what most of 
us thought in the first place. 

I thought the answer to this was pretty interesting. The Order 
members use their Patronuses. DD is the only who knows how to use 
them this way and he taught the spell to the members. She gives some 
other information too.

So, without doing so, she answered some other questions:
Can Snape conjure a Patronus? Many readers suspected he couldn't. Of 
course now the new question is "What is Snape's happy thought?" 

There was also some doubt about Lupin being able to conjure a 
corporal Patronus. But this would indicate that he can. 

I will presume however, that neither Hagrid nor Mrs. Figg 
can....although it would be interesting if DD taught Hagrid how to.

Something new to discuss just as time is running out...
