Hello again!
To answer a reader's question: we need both your first and last names because if we get more than one of the first names we won't be able to clarify who is who during the names-in-the-bucket process. So it's just to help us during the name-choosing process.
For example if we get Sarah, Sarah, and Sarah entering...we don't really know which Sarah is which. Hope this helps to clarify! And don't worry- none of your comments will actually be posted on the blog. So no one will know what your full name is besides Penny. :)
Keep those questions coming!
