Registration issues

Thanks, and for 1) I would suggest to rename the option analogous to the surrounding ones:

Now:
[v] Receive emails from the Administrators.
[ ] Hide your email from other members.
[v] Receive private messages from other users.

Future:
[v] Receive emails from the Administrators.
[v] Receive emails from other users.
[v] Receive private messages from other users.

That should make it clear and remove any future doubts like that.
