When I saw the name of this topic, the first thing that came to mind was the song 'Beds are Burning'.
I have no idea why, and I bet you didnt need to know it.
But anyhows, the answers to your question, in chronological order.
- Re-read all the books, at least three times.
- Bombard JK Rowling with mail, begging for more.
- Re-re-read the books.
- Read Lord of the Rings.
- Re-re-re-read all the books, while waiting for the final movie to come out.
- Sit and cry because its all over.
- Watch all the movies again.
- Sit and cry because Dumbledore just died on the screen.
- Try and blackmail JK into writing more.
- Re-re-re-re-read the books.
- Spend half our lives doing re-makes of the movies.
- Try once again to get JK to keep going.
- Decide that LotR was better in the first place, and go re-re-re-re-re-read
The Silmarillion, and learn Sindarin.
I might skip from the first to the last, but you never know.
Or maybe I'm already at the last. At least Tolkien didnt accidently kill off the best characters. I swear that was a mistake of JK Rowlings...
