Believe it or not, I was once a "newbie." Lol. Most of my emails start with txtilde@.
The reason for that is because whenever I would give my home page url, which was my 14.4 dialup's free homepage they gave me, it was
http://www.domain.com/~username/
I kept saying saying h, t, t, p, colon, slash, slash,
www.domain.com, slash, wavy line... and being from texas... they called me txtilde. Took me a long time to live that one down =)
I can laugh about it now, but I certainly know what it's like to not be "in the know." As it stands I learn something new everyday... no reason I should ever jump on someone else for something I just happen to know. Who am I to say it's "common knowledge?" My parents don't know how to register domain names. I certainly don't think they're stupid.
