You can open the "contact_us" template and put the form in a conditional...

Before the line:

<form action="sendmessage.php?do=docontactus" method="post">

Put:

<if condition="$show['member']">

and after the line

</form>

Add:

<else />
<div align="center">You must be logged in to contact us.</div>
</if>

That should do it...

BUT...

This is a really bad idea, you need some way for people who can't login to contact you- what if they have login problems, can't register for some reason, or someone not a member has important info you need to know... That is the purpose of this page. If you limit it to users at the absolute minimum you should include an e-mail address as part of the "You must be logged in to contact us" message above.
