I'd love to reactivate the certification, but time is the problem. Back when I got certified, I had one child... now I have five (all daughters!) While they're young, they need and want to spend time with daddy. However, when they're teenagers and the old man just embarrasses them... I'll have time!
To keep your certification active, you have to teach a minimum number of classes per year, and I just didn't have time to keep it up. It was fun, though.
