Harry Potter-19 years before or after

for the people who've read hp7...might resent the huge gap between extermination of voldemort n the happily ever after scene.I have grown up reading hp n the 7th book marks so many things in my life as well...i turned 18(officially a major),etc etc etc
..any ideas bout wat happened to the others or wat happened in these 19 years...times of india gave us the careers of harry, ron and hermione...nuthin said bout luna lovegood, lee jordan and so many more
does mr.weasley beacome head of muggle dept,et all...
fill in with your own predictions about any and every character tht J K Rowling failed to mention...

I think JKR has given most of this information on net interviews, though i cant remember where. I think Luna ended up as the owner of teh Quibbler (obviously) and went on some research for "dont know how to pronounce" things.

No info on Mr. Weasley though...maybe he became the minister of magic
