I've just recently downloaded and installed DotNetNuke 3.2.2.  I'm very unfamiliar with the package, so hopefully this isn't an obvious item...

I set up some links on my Home page of my portal.  I was just playing around and later deleted the module that contained the links on that page.  A little later, I was looking through the database tables (familiarizing myself with how it's put together behind the scenes - I'm a developer also) and I discovered that the links I had entered were still in the database, in a couple of tables.

Is this expected?  I could see keeping the data around if there were a mechanism to select previously-entered links into a new module (say, on another page, or something), but I couldn't see how to do this.

Is it expected that one should delete all of the links from a Links module before deleting the module itself?
