Hi Jim,
no you're not doing anything wrong!
At the moment the Membership section is only accessible to myself and the site creator for update and admin purposes. It will at some point be brought online for everyone else. The site has the capability to run an online store, paypal and all that jazz but really I haven't even considered the commercial scope yet.
In the meantime, if you have subscribed to the Newsletter you'll get automatic e mails with FREEBIE updates such as rules etc.
If you are registered in the FORUM you can post(as obviously you are Jim!)
So currently you are not missing anything
Cheers
B
