Take it for what it is...
1) Upset that registration failure deletes entries.
2) Confused about "creative commons" acceptance.
3) Wants required fields to have asterisk.
4) Homepage URL doesn't allow characters like hash and exclamation, which unfortunately are used at Facebook.
As an admin I know I can change the acceptance but it would also be nice to be able to remove it. I'm going to add some brief text above the prompt to clarify what it is and to indicate it's a required check.
