You just send them to
www.ticketsclub.com and they log in
Since the join page also has a reduntant log in form for return buyers, I wonder if they could make the log in page and join page into one - should streamline the process
(I.e. if someone goes to ticketsclub from my log in page, they can already join from there instead of having to go back to my site, find the join page and go back to ticketsclub...)
