1. The hacker won't know which lists you are subscribed at. But the worst point is that I don't know exactly how to forward this kind of requests. Direct RSCS send? That's some 100 files generated in a few seconds. A crazy NAD can fill up all your spoolids with that kind of things, without even realizing it. DISTRIBUTE? That's a lot of overhead for 2-recs files. 2. I still have Doron's private mail about WHEREIS in my reader, it's just not the kind of thing I like to implement in 2 hours. I want it as part of the DATABASE support, ie distributed database facility. Nothing prevents LISTSERV from searching its own databases internally :-) Eric
