I always thought that when referring to colleges that it is best to first state the full name (and city/state if need be), then the abbreviation - refer by abbreviation for the rest of the thread. This would avoid confusion. The way it is done in a college paper, also the way they are identified on Wikipedia, for example.
D12 is daughter graduated in 2012. Get it? D2 means second born daughter. D1 is first born daughter etc.
S1 is first born son. DH is dear husband. DD is dear daughter etc.
I’m seeing “LOCI” in the waitlist threads now. Assume it means something like Letter of Continued Interest?" Is ther something labelled that in waitlisted “packets” to fill out, or do yo just write a letter? (D has three WLs and I haven’t seen something labelled LOCI that I recall, yet.)
I wonder if D212 might mean "second daughter who graduated in 2012? Or should it be D2U12 as second daughter who graduated with undergraduate degree in 2012? Just kidding:)
