How to?

Hey guys,

I search the forum before deciding to ask. My question is, is it possible to edit the registration form:
- to collect First and Last Name
- set to inactive the Subscription Level / Membership Level untill approved by admin

What I'm trying to do is have people sign up (for free) but not let them see the content until i approve them. But without the First and Last Name, I won't know who to approve.

Thanks,
Dat
