If you keep the smaller www.club-zoa.com in the lower right, you might want to have www.club-lps.com on the other side for consistency. Personally, I don't think either is needed. We all overlooked the address at first (kind of funny actually), but if we took the card home and started to look for the website, I think we would quickly realize it was right in front in big letters. Plus, we are all active members, so we may have just glazed over the address b/c it's familiar.
