[Mapserver-west] user defined map point

Hi Jeramie,
It's always good to hear from you.

Are you using the CGI version of MapServer or are you scripting it?  I'm 
guessing it's the same as you were using earlier which was straight CGI.

Sorry, but I don't have an example for you on this one.  It's becoming an 
increasingly common question though, for sure.  I've seen an example of 
exactly this on the Chameleon mailing list.  In fact, with the Chameleon 
mapping framework it has a tool for doing this very thing.  

You can see it in action on this demo:

The top-right tool (a pin with a "+" sign) allows you to click a point on the 
map and enter text.  The printing functions are also really great.  Chameleon 
using PHP and comes with all this functionality "out-of-the-box".

Hope that helps!
