Fellow witches and wizards! Welcome to your Common room!
Pull out a lounge chair and tea! You'll have your discussions only in this post aka your common room.
As you're aware about the troll in the dungeon, the MoM requests you to stay safe in your common room. Prefects, Head boys and girls, the professors and the headmaster will be monitoring the common room closely.
Don't ever roam in the corridors (aka making posts) as the corridors are not safe for a while. Anyone who makes posts will be warned and all the other posts will be locked. Stay in your common room with your friends and classmates while the issue is being handled.
All the Quidditch matches and the events are cancelled due to the same reasons. Don't try to go to the pitch at any cost. All the games are to be postponed until announced.
All the first years are to be guided by the seniors to stay in the common room. Everyone consider the seriousness of the issue and stay in the common room.
Don't ever try to go to the Dungeons. Or talk of the being in the dungeons. Anyone who shows interest about the creature in the dungeons might face interrogation and the interrogation won't necessarily be nice.
Here is the link to the first announcement in case you haven't read it or you didn't understand the first time:

Even though the Hogwarts Hallway, classes, and other locations are under curfew, the activities, academics and other regular happenings won't stop. Don't loiter around as this is not an OT post. Prepare for your O.W.L.s, N.E.W.Ts and other works.
There'll be an announcement when the corridors and dungeons are safe again.
Anyone who breaks the rules will get killed, or worse, expelled.
(Aka warned/blocked/even banned)
