Integration with Rules?

Hi;

I had posted a general question here: http://drupal.org/node/787628 "My client has a business directory site (focused mainly on nonprofits) built with Drupal 6. His plan is that this weekend he is going to have some volunteers all log into the site using the same username and password to post nonprofit listings.

Then on each listing he wants a graphic link that reads something along the lines of "Is this you? Click here to take over this listing"; upon clicking on that link, they'll be taken to register for the account and that listing will be automatically assigned to them as though they were the original author, granting them access to edit any information in that listing right away."

This module, along with the Claim Node Ownership (http://drupal.org/project/claimnodeownership) module were both suggested to me as possible ways to make this work. I've installed both modules, but I need help getting further integration to make it work exactly the way we're wanting it to?

When I set the permission for anonymous users to claim ownership and tested, the node author was simply changed to "Visitor", without ever directing me to register or create an account. How can I get this set so that only anonymous users can claim ownership of a node, but before the node's author is changed, that anonymous user is taken to register for an account?

Thanks
