I have no answer to your q. but I would like to ask you if you know where one can get a copy of Linux+ learnkey collection. I've got some of the learnkey stuff, well quite a bit actually, but none linux nor unix, I woldn't mind to exchange copies. I've got lots just ask for a few if interested, I,m sure I could come out with one of interest to you.
