Two requests from a new member

[Guy Betten]

Hi people, I am new here and having a few issues which should be a easy fix, lol.
1. Where do I open the option for member to email each other? This is the message I get when I try to email a message to a user I created (w/o admin rights) to do tesing.

Sorry! That user has specified that they do not wish to receive emails. If you still wish to send an email to this user, please contact the administrator and they may be able to help.

2. Where would I set up ALL visiters to register first, before being able to view my forum? Where they would get the following message.

You are not logged in or you do not have permission to access this page. This could be due to one of several reasons:
You are not logged in. Fill in the form at the bottom of this page and try again.

If you are trying to post, the administrator may have disabled your account, or it may be awaiting activation.

The administrator may have required you to register before you can view this page.

Thanks in advance, JPT.
