ber, nobody taught me to "use" linux/SME and command line.. I just tried and tested and I made many mistakes.. so, please, don't be shy to learn, try, ask..
just remember that there's a good probability that your problem/question has already been solved, so you should really spend some time to search.. I found the link I gave (and you did not tell me/us if it solved your problem) simply clicking on "search" link, writing "dar email" in the text box and.. that's all..
I suggest you to spend some time to install a virtual SME to test.. without the fear of damaging something, you'd find yourself more confortable.. and once you start using CLI, you'll be surprised of the power that you gain..
ciao
Stefano
