A little OT, but everytime I see a post like this, I mumble to myself: "Don't make a mistake when updating SURBL!" :) Obviously we want no FPs. Jeff threatens to hit any contributor of an FP to SURBL with a clueby4! One guy entered 5 FPs once. No one has heard from him in a while, and Jeff just giggles when you ask about the guy ;) I've received more satisfaction out of my open source projects then any job I have ever had. WHy is that? :) Chris Santerre System Admin and SARE Ninja http://www.rulesemporium.com http://www.surbl.org 'It is not the strongest of the species that survives, not the most intelligent, but the one most responsive to change.'
