I have a full dmoz dump that has a cron function to update. The coder set up all the cron functions in the files, but omitted to set the cron tab and I can't get hold of him now. He ran it fine in testing so Iknow it's just a question of enabling it. Shouldn't be too hard for knowledgaeable coder. Just look at files and configure cron tab. I will check if updates have worked via MySQL records.
