Does CiviCRM ship with or have an extension for a donor wall? If so, how well does it work? If not, what is a good solution for creating and managing a donor wall that will work with CiviCRM installed under WordPress?
For wordpress I think you will have to write some custom development. I tried to use a search profile for this but found it was lacking. Perhaps you can figure it out but with drupal there are many possibilities. The code reference is very old but may get you part way there. I think this would be a great extension if you have funding.
