Cool. I've been a member of the Kink site in the past and found it to be fast and well done. Did you just work on the back end stuff or did you also work on the design/layout of the site as well?
I did the backend stuff, but wrote a lot of the jsp pages as well. It is all Java/J2EE/JBoss/EJB3/Hibernate with some fairly complicated single sign on stuff going on to allow cross domain auto-login.
