How do i delete the rss feed in wordpress

Hi,

I’m running a secure wordpress installion where i have users registered and they are all subsribed via the profile to receive updates of the site. I wish to remove the rss feed (www.yoursite.com/feed) so i can place a page there that says rss feeds have been disabled but you can subscribe via your profile.

The reason for this is i can’t have anyone giving the feed out so “outsiders” can get in and reads what is being posted.

Anyone got any ideas? Which code do i remove?
