Discussion Board permissions - Access to only reply to threads, no

Is there a Sharepoint Solution for a discussion board that would restrict
Users from creating new threads while still enabling them to reply to threads?

I am open to all suggestions, not just limited to Discussion Boards.  I have
considered Blogs as well as creating a Moderator to approve new threads.  I
have played around with the permission levels and it seems that Adding a
comment to a thread is conclusive with creating one.  If you can reply to a
thread, you have the ability to create one too.

Basically, I have a user that wants a Discussion Board where only she can
create new threads and have the users reply within those threads.  She's
being a real PITA about it and insists on using Akiva WebBoard.  Thanks

Forgot to mention we are using MOSS 2007.

I only have WSS 3.0, but I think the blog template is the same for both WSS 3.

WSS 3.0 and MOSS 2007... If you change the permissions on the 'Posts'
library, you can limit the posts to only a group (or an individual) and
then leave the 'Comments' list as is (so, for example 'Members' have
contribute) and you will meet your requirements.
