Hi,
Following the discovery of the Wikipedia backups from 2001, and with much appreciated help from Jospeh Reagle, I created excel files from the diff_log and rcl_log files that together include all the edits from January 15th to August 17th (the last in the backups). the files include the time of edit and the editor's username and IP. While they are a bit buggy, and could use some more editing (or preferably, conversion to wiki format), they are simple, easy to work with (using searches and filters), and full of interesting stuff.
If anyone is interested, I'd be happy to share them.

Lior
