The files were Drupal 6 files in the Drupal 7 version. We have updated the files to Drupal 7 version. Now Downloading the Drupal 7 version files will give actual drupal 7 files.
Functionalities in this release:
1. The administrator can set the content types which could be claimed by user.
2. E-mail will be sent to admin/user when the user claims for ownership of node and when admin approve/reject the claim.
3. Administrator can customize e-mail body and title.
4. Once the module is installed and configured, the link for claim would appear in the node.
5. One user can claim multiple nodes.
6. Once the ownership of a node is given to the user, he would have complete control of that node.
