Greetings Everyone,

I'd like to thank everyone for the helpful replies and the warm welcomes. :) 
I havent fully had a chance to fully review the responses or finish the 
script, but I dont think it will be terribly hard now either.

And to those who had asked - yes, I do have the handles column set to 
"unique".  Forgot to mention that in my initial email.

Seems like a great list you have going here.  Glad to be a part of it.

Thanks again,
