Congrats to all the admits! You're in for an amazing experience. Now go sign up for admit weekend as soon as it becomes available.
Good luck to the dings. Pretty much everyone gets at least one ding and most of us get lots of them.
As for you R1 WL's, I'm not involved in this part of admissions, but based on conversations with my classmates it looks like a pretty good place to be. If Booth is really where you want to be next year, I think it pays to show them some love. Last year on the day I interviewed (R2) there was a married couple from Europe on the R1 WL who had flown in to visit and meet with an admissions officer to express their interest. They were admitted with me in R2 and I see them on a regular basis. I'm not saying that is what everyone should do or that it's some guaranteed trick...perhaps it's coincidence, but figured I'd share.
