Hey, I thought I'd say hello. I used to hang around the site a lot years ago. It's been a long time, but I still recognize some of the names in the forums from back then. These days I'm working on a PhD in Applied Mathematics. Man, has it been a long time.
Back when I was still active, I remember updates being few and far between, but now I see you've all got new sheets all the time. Kudos to you all for the hard work and productivity- new members and old, you're all doing amazing stuff.
I ended up back here because I was telling a friend about this site. I probably won't post very much at all (gotta write my thesis!) but it's nice to see everything that's been going on!
