Activating subscriptions!

Hey All,

Having some trouble getting my head around the Membership plugin.

I have done:
~ Set up Levels
~ *STANDARD & *FULL
~ Created Subscriptions
~ *STANDARD = Free for a set amount of time (serial - 1 day for testing)
~ *FULL 6 months = $xxx (serial)
~ *FULL 12 months = $xxx (serial)
~ Setup Gateways
~ Paypal Express (sub, active, live site)
~ Setup Options
~ Stranger = *STANDARD
~ User reg = none
~ Reg page = set
~ Acc page = set

I'm struggling with:
~ How do I up sell to new members on sign up? I can't find the subscriptions links/buttons to create a custom registration page. At the moment there is the standard sign up page/link that puts the new member on the *STANDARD level.
~ When using the [renewform] it returns a "You do not currently have any subscriptions in place."
