Auto-fill and lock Contact form
This will auto-fill and lock (as read-only) the contact form with reg. email and user login name. I feel this serves to better protect the seller, as there is nothing to stop someone from using en email and username not registered on the site. You can still mod your theme-emails.php as done
here to pull the info into the email. I think it's the sidebar-contact.php file (IIRC):
<li>
<label><?php _e('Member name:', 'cp') ?></label>
<input name="from_name" id="from_name" type="text" minlength="2" value="<?php echo $userdata->user_login; ?>" readonly="readonly" class="text required" />
<div class="clr"></div>
</li>
<li>
<label><?php _e('Registered Email:', 'cp') ?></label>
<input name="from_email" id="from_email" type="text" minlength="5" value="<?php echo $userdata->user_email; ?>" readonly="readonly" class="text required email" />
<div class="clr"></div>
</li>
