Well, unless I'm doing something wrong, the first suggestion takes me to the main web site of my domain, I think all it does is telling the server who the user watching the site is.... If I use that, all usernames@mydomain.com go to the same (the main) site...
And the second option wokrs for Ibays... But not for usernames.... unless you create subdirecories in the main site with those names...
What I was talking about is more like a public html folder inside of each user's home directory in which the can put they're web pages...
Thanks!
