If you're coming to MiniCon, you can now officially register! I know! Very exciting stuff. :o)
We are inviting people to show up at the last minute and pay cash at the door, so registration isn't strictly necessary unless you want to secure a spot in a workshop that has a maximum (and you'll need to pre-pay for those, too).
I hope you come, I really do. And if you don't come, I hope it's because you're going to OCON, or otherwise spending 4th of July with other like-minded people. :o)
