Drupala since '05. I work for the e-Learning Institute @ Penn State (http://elearning.psu.edu) and have developed several projects which are now open source and posted up on Drupal.org. I'm currently porting my module set from 5.x to 6.x and have started porting some of our courses / sites to 6.x.

I was at Drupalcon Boston and made some great contacts in the Educational community and hope to present / do it again this year! I also hope there's a bigger focus on libraries / education / LMS development at the conference because there were a lot of people I knew clamoring for it and not much discussion there of.

Useful links / things I work on:

Here's the d.o. projects that are out there I've done or worked on:

http://drupal.org/project/slicedbook_navigation

Hope to meet up with you there!
