Great.  Thanks.  How does it know "within 500 miles of my
location" when I am just browsing on the internet?  Do I need to
ID somewhere?

If this gets popular, I wonder it there could be other sub
categories of bulletins.
I couild imagine things like this being used:
BLN#MDNOW  <== for state of Maryland and a live event
BLN#MDMAY  <== for state of Maryland and something planned in
BLN#MD-25  <== might be an even in Maryland on the 25th of this

So maybe, SORTING and GROUPTING by the actual BULLETIN group
might be another way to discriminate these.  Originally I had
proposed putting the state and time/date as the first part of
the bulletin.  I wonder if making them part of the BLN GROUP
name might be a more consistent way to do it?

Just some ideas.
