Entering DWR Challenge

Could someone please help me... trying to enter the DWR Challenge.... I don't have a blog or website and the form asks for my URL link.... Victoria suggested i post on this site and then go from there, but I still haven't figured out how to make the transition.  Not sure what I'm supposed to "copy and paste" for the URL... Any smart computer savvy friends out there who can help me?
Thanks.
Jody
