Assuming I have access to a ManilaWebsite table, I would like to write a script that gathers some stats to indicate the most active of a set of sites. For a particular time interval (last week, for example) I would like to be able to total (separately) the number of news items, comments, and discussion posts without including those items that are actually images. Can anyone suggest an approach? It's not immediately clear from the site table how Frontier tells these things apart.

This is a Manila site... http://manila.userland.com/.
