I am sorry for my slow response. I have been studying all summer for a Certification exam. When you wrote, we were in the middle of taking the exam, and now, I am working on a deadline for the TL conference paper.
Years ago, there was a youth hostel up town and I believe it may have been on Amsterdam avenue in NYC.
I am not a student member of any TL group at Columbia. I am not aware of any group. Good question. I recently applied to this TL network because I will be presenting at the conference in Oct with some fellow classmates.
