Congrats to you, fullbrighter!
On another note: this may be sort of useless to everyone else, but I called Penn today and they informed me that they have been sending out accepted/rejected notices to WL students for a few weeks and that they are going to continue to do so for the next two or so.
I was also told that I wont have a decision on my file. They're keeping me as "Waitlisted". Huzzah
