Vanity trap: paging John Vulner

I’m having a little trouble tracking down John Vulner, Northeastern U CS grad and a sometime co-op in my department. I’d like to get back in touch. Best I can tell is that he works or worked for Microsoft after graduating in 2006.
John, it’s James (I guess that may not be apparent from this site…I should fix that sometime). If you’re Googling your name and find this post, please drop me a note. jls at jls dot cx will work fine.
