[Qgis-user] adding points within polygons

[rsweeny]

Brent
So kind of you to respond. I am afraid "geometry tools" is not an option 
on my Vector pull down menu or toolbar. Do I need a plug-in?
I quite agree with you about the centrality of a proper relational 
database underpinning the gis. It is getting from one to the other that 
is giving me the headaches.
