Otherwise, a nifty program called mhonarc will take mbox files and turn them into threaded HTML page archives. I have mail going back to 1991 that is all searchable and threaded -- very nice. -- Jim Leonard (trixter(a)oldskool.org) http://www.oldskool.org/ Want to help an ambitious games project? http://www.mobygames.com/ Or check out some trippy MindCandy at http://www.mindcandydvd.com/
