^ -.- it is not hard to appeal.
It does not hurt to try. The worst thing that can happen is that they don't accept your appeal (I think they even give you a reason for not accepting you, which can be potentially benefiting for your future applications) Of course if you do not have "new" information, include it! But if you do not, i still encourage you to use my advice. For any reason: If they do not reach their acceptance quota, if a different reviewer feels you should get in, there is always a chance you can still get in. Submit your appeal and do not regret it in the future!
I do think is that hard to appeal.

A lot of people want to appeal just because of the reason they really want to go there; it doesn't mean they qualify. And most people don't get accepted through appeals. It's one thing to appeal, it's another thing for your appeal to get your appeal accepted. The stats are incredibly low.
guys....what you write on an appeal should be more personal than anything *edit* personal as in non-generic? idk how to explain lol
this isn't just a college essay and asking someone "what should i write" isnt going to help you much because that's for you to decide.
i agree completely with chinese tears...don't just blab on about how much you like the school and really wish you could go because that's just like something you could have put the first time around and, to some extent, were probably asked to write about it. i don't think that will get you very far, but that's just my opinion
I don't know if our opinion of "personal" is the same, but I think this is true too. I've heard of people who were really persistent and got in. This guy didn't get his appeal accepted and he wrote them another letter and then he got in, haha. It might because they realized he really seriously wanted it or he provided even more information, I don't know. I think your sincerity and want to go to that school really makes a difference. This really can't be a "tell me what to put so I have a better chance of getting in" thing.
