Remove links without blog posts

Your weekly module is fantastic, just what I was looking for. I'd like to make a request:
It would be better if the module omitted links for weeks when no blog postings were made. For example, my blog started in august 2004 and i have a large list of links in my weekly archive block. Approx 1/2 of those links contain no actual blog posts because I didn't blog anything that week. It would be better if there was an option to remove these blank links.

Also, I second the motion for a "monthly" option in addition to weekly.
