It has to do with the number of posts. Rather than have something like Newbie, Junior, Senior, it's related to knitting a pair of socks. The more posts, the farther along you are on your 'socks.'
"Trust the pattern!"
Time flies like an arrow, but fruit flies like a banana.
Hop aboard while we follow the cloud-covered van of knitting harmony, man!! Woooo!! --Hedgehog
