How difficult would it be to make a program like "mapmyrun.com " where you can map out spots on Google maps and it will save it to a data base, then intergrade it with Vbulletin so that when you make a new location it creates a forum post. All the viewers would be able to see the the locations and if clicked it would bring up the forum post. is it possible?
You will need to do your research into the Google Maps API, which means you'll need to code some good JavaScript and Ajax to get the layers working correctly. When you map out a spot, which in Google Maps speak is a Marker, you will need some PHP (via Ajax) to send the marker information to the database and create the forum post.
