don't remember registering for this site!?
Don't worry, there's an explanation. Here are two likely possibilities:
- Former Puzzle Center users
Until the summer of 2002, the Puzzle Center center used a separate registration
system. We've merged the two for your convenience!
- Trade shows or conference attendees
If you gave us your e-mail address at a trade show or educational conference of any kind, you were also signing up for a free subscription to our sites and newsletter
Feel free to contact us at firstname.lastname@example.org with any questions or comments!
