Web-savvy people: how hard is it to do something like....

Collaborating with others

Once you have created a map, you can invite individuals or anyone to collaborate on editing your map. To do this:

1.) Create or edit a map.
2.) Click Collaborate in the left panel. A dialog box appears.
3.) Enter or choose the following:
......Invite persons as collaborators - Enter the email address(s) of anyone you want to collaborate on your map.
......Message - Type the message you want to appear in the invitation to your collaborators
......Collaborators may invite others - Check this to allow your collaborators to allow other collaborators
......Allow anyone to edit this map - Check this to enable any Google Maps users to edit your map
......Collaborators - You can remove any or all collaborators
4.) Click OK. Google Maps sends an invitation to any collaborators you specified.

I've been kicking an idea around for a while for a photo project.

The project would require me to solicit submissions from other people.

I might want to Google map the results.

Is it hard to learn how to build and run a web site like that? Is there some kind of a map program that you can tie into that if you post, say, a particular intersection that it will record it as a dot?

To be honest, I don't even know the right questions to ask about such things so I'm hoping someone can gently steer me in the right direction.

Thanks
