I'm trying to renew membership, using the "Membership" link at the top of the page. When I press the 'Order' button after selecting a one year term, however, I get a "Page cannot be found" error. Am I doing something wrong, or is this some sort of problem with the renewal page? Hey, I'm just trying to do the right thing and stay a member - I get so much from this site, I don't want to be a freeloader!

Thanks, Mark
