Membership plugin

Hello,
I've upgraded to RC2 - I just uploaded and replaced files as I couldn't see any upgrade instructions.

It's mentioned that we can add gateways easily but I have no idea how to do this. The only gateway has USD fixed as a currency, even though I have specified a different one in the options.

Also, the default subscription form seems to start at step 2. What did I miss?

I have searched the forum and couldn't see answers so any help gratefully accepted.

Thanks.
