urlstatus question

[Ron]

As you know Andre, I'm a complete rookie when it comes to web stuff  
but I have benefitted greatly from the contributions of list members.  
Rev enables me to go to places I could not have gone before - like the  
web - but I need the help of others and this list is a great source of  
help.

Thanks All,
Ron
