Thank you for everyone who has participated. The Chamber of Secrets has been closed.
To solve the quest this is what you had to do.
1. Goto http://hexrpg.com/diaryoftmr.html and talk to the diary. The keywords were "who opened" and after that "i hear more"
2. Then when you goto Hagrid's hut you would then would be able to read about how Hagrid was taken away and then you'd be able to talk to Aragog.
3. The keywords when talking to Aragog are "you monster?" and "attack"
4. After you talk to Aragog you would receive a random event about a flooding bathroom.
5. You then goto http://hexrpg.com/bathroom.html and when you click on the urinal closest to the sink it gives you a link to the chambers.
6. Once in the chambers you then must "run" from the Basilisk, then "slash" and then "stab" in that order and you would receive Tom Riddles Diary.
7. Then you go in your inventory and stab the diary. You then receive your houses sword.
You can no longer receive a prize for winning. If you tried to stab the diary and it said the action was being worked on then you were too late.
