Site registration open for Teach a Friend to Brew Day

I've registered my "site" for Teach a Friend to Brew Day. What does that mean? The AHA can count the number of participants and let us all know how many others were doing the same thing on that day. I suppose it gives them numbers to post each year about how there is a growing trend in homebrewing. By the way it doesn't look you have to be a member or anything.

Why am I doing it? Eh, I guess its what I do. I enjoy brewing and teaching people. So why not?
