Right on with the linux and unix crew, wish i knew as much. My beef with the whole computer thing has been this, the computer books written and the instructions given for any particular thing delaing with computer looks like it was written in chinese, when come to find out there are simple directions for simple minds (like mine) to do the same thing. And unless you were part of the GEEK ELITE, there were no answers for you. Someone made the jump for us UNDERGEEKS and authored the "DUMMIES" series.
Geek speak: information about the blah blah blah blah , such as who authorized the certificate, its public keys, and its expiration information. Blah blah blah blah certifying authority (CA), such as VeriSign, GTE, or AT&T. As a user, you can look at who certified the object and decide whether to download and run the object. It is most important that you trust the certifier, or you could end up with someone maliciously infecting blah blah blah blah blah blah.....
Normal human speak : Right click My computer.

KISS for me. (Keep It Simple Stupid) Im just a squirrel tryin to get a nut.
