WordPress users report

First you have to make sure that this information exists in your Wordpress database.

If the user has subscribed to the common Wordpress registration form, this information will not be available.

In case if it has registered from some plugin that you have, the plugin itself would have to show you this information.

The best thing to do is to enter the database and see what table that information was saved in and run a SELECT * query from YOUR_TABELA, so you could view the information.

I do not know if this is what you wanted, otherwise try to rephrase your question, I have used Wordpress for a long time and I know his database well, this type of registration form is not his standard.

Edit: You can also check for some options in "Tools" in Wordpress, I believe it is difficult a plugin that just register but does not display what you have registered.
