I think Yarnspinner's first post may have been made in the time before the GUEST feature was installed in the Mudcat. At that time, everyone had to type their name in a box above the text box every time they posted, and there was no GUEST in front of it. There are a lot of posts of that type. I'm not sure exactly when the member cookie feature was installed, but I think it was sometime between December 1999 and June 2000.
