How to edit VB message when not logged in

[mgcom]

I've now requested that everyone must register on my forum before they can read posts.

I'd like to change the VB 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:

1. You are not logged in. Fill in the form at the bottom of this page and try again.
2. You may not have sufficient privileges to access this page. Are you trying to edit someone else's post, access administrative features or some other privileged system?
3. If you are trying to post, the administrator may have disabled your account, or it may be awaiting activation.

I know its in the phrase manager but not sure which one it is

Please and thanks
