Is there a known-solution or known-theories for giving users access to change only one story? This would be a way to allow businesses in my directory to update the listings, once I 'prime' them with some sort of startup content.
Example:
I would love to give a login/password to the owner of Drawing Board, so s/he could edit this listing I started for them. They are a lot more artistic than I am, but obviously, I cannot have them touching anything except this one story.

Sorry if this is too simple a question. Looking at the security/permissions parts of Drupal, I am thinking there has to be a way to do this, but I don't yet see a way to put together a solution for this scenario.
As always, any assistance that might be provided will be appreciated immensely.

Author
Make an account for them and make them the author. There's an "edit own" permission. As admin, you can always make changes to it without being the author. That's how I handle it on my site.

Automation
Is there a way to automate this?
What I'd like to do is create the business listing and input some basic info myself. Then have a script or possibly a module that would create a user with the businesses email address as the login. Then make this new user the author of their listing and allow them to only edit their listing. Then send an email to said business giving them their username/password and the current information thats in their listing. In the email I'd also like to give them the url to their listing (the business node) and tell them how to edit it.
Is this something that could be easily done by someone new to drupal? How about a seasoned vet? Any info on where I'd get started with something like this would be awesome!
More thought
After thinking about this all day I think the actions and workflow module 'could' be perfect for this.
1.) Create a business listing
2.) Move the listing to a new workflow state which would trigger some actions
3.) One action to create a new user
4.) A Second action to change the author of the business listing to the new user
5.) A Third action to send the email to the new user.
I guess it could be easier to wrap this all into one action.
Then the Content Access module would be used to allow only the author of the business listing to edit it.
I've poked around a little, but it doesn't seem actions are all that popular. I can't find many user created actions. I did however find a tutorial on how to write your own actions. I think with some fooling around these actions could be created. I think that automation for this is essential, because doing this manually would get old quickly.
Thank you
Perfect solution. Thank you Michelle.
