Newbie Help: What to do about subdirs in a Module?

Hi all;

I'm new to CVS and I have inherited a repository left behind by another 
contractor

$ cvs version
Client: Concurrent Versions System (CVSNT) 2.5.03 (Scorpio) Build 2382 
(client/server)
Server: Concurrent Versions System (CVS) 1.11.23 (client/server)

The repository name is "DSA".

Within the repository I got a list of modules by running
$ cvs ls

There are modules for other groups beyond my own, then there is a 
"module" for my group called:

"BDS"

Within this module "BDS" the prior developer put a number of 
subdirectories.   Each subdirectory is an independent software project.

I am wondering, what if anything I should do about this.

So far, this arrangement confused me until I figured out what he did.

I like the idea of keeping all of my groups projects under something 
called "BDS" since that is the name of the group.  However I am 
wondering if projects as subdirs in a module named "BDS" is a smart 
thing to do.

Would it better to create a repository "BDS" instead?   Is it possible 
or smart to create a child repository called "BDS" under the parent 
repository "DSA"?

I'm a newb, just trying to sort all of this out.

Thanks

Steve
