[TxMt] Re: SVN?

[Ethan H. Darling]

Jacob,

I strongly agree with your statement about web designers/developers  
not embracing version control.  That is why I'm trying to be as  
counter-culture as possible.
I just started a degree program for Website Development and  
Management and I'm shocked to learn that at no point in time will the  
curriculum topically address version control.
So, I'm on my own and that is what triggered this thread.
Your observation has really encouraged me to continue learning about  
SVN and integrate it into my professional toolbox.

Thanks,

Ethan
