I am a little confused about the prize claim process.  I got a PM with a link, went to the link and filled out the form and clicked "accept."  But it was kind of weird that I didn't get any acknowledgement that I submitted the form.  Also, for an Instructables prize pack prize (which includes a shirt) shouldn't they ask for a shirt size?  When/where/how do they do that?  I guess I am just worried that maybe I am missing something. Or that the form isn't being submitted properly. Or maybe I'm just being impatient.
