What is a Carnival of Homeschooling you ask. I was asking the same question not too long ago.
Here's how it works. A different blogger hosts the Carnival each week. This week's host is Why Homeschool. In the week leading up to the Carnival, the host searches for helpful posts from other blogs to feature. For example, there is a link at the Carnival to my recent post at The Thrifty Homeschooler about homeschooling conferences.
