You can talk about your admits in the respective school threads that already exist AND you can update your profile accordingly in the other threads. I dont see the need for another thread.
I can try to explain. The real issue is duplication. We struggle to organize the information all the time. Duplication is not taken kindly to in any forum. Just think of the chaos if everyone tries to have their own thread going about the same topic. It is a vicious cycle. The more decentralized the information is , the more difficult it is to find what you want and more duplication will occur as a result. We cannot blame joe_new_user for posting a question about something that has already been discussed, but is difficult to find.
The moderators serve as examples, not as cops. We want to be inclusive and sometimes this intent is not as obvious over the internet when we cannot see the person we are communicating with. The best forum is where no one ever feels the need to display authority. But this cannot be a one way street. We need to take care of each other and respect each other more.
As for discussions, I don't see any issue with facebook/ biryani or any of that type of discussions. All of you are real people, not robots. As long as your comments are in good taste, go for it.
Be nice. if you are not sure that something will offend, simply don't do it. People cannot hear the nuance in your voice, in your tone or on your face.
As always, if you screw up, you will know.
