Registration shortcodes

Hello there,

First of all, thanks a lot for helping me out with the plugin installation last week.

I do have few questions if you don't mind:

1. How can I get the registration page to work, when I click on it, no form show up?

2. I'm trying to setup memberships plan on my site in a way that members try it for two weeks only, then the payments takes effect immediately according to the plan they sign up for. Can that be possible with the membership plugin?

Cheers,
Jeremie
