Hi wardari,
the short answer is: you can’t. I mean that, as things stand now and without modifying the plugin code, you can delete users only by deleting the relative row into DB (seplog_users table); also, you could suspend users, so that they will not able to login until you’ll decide.

Will there be a delete button in the near future? It becomes a problem for me when I need to recreate a user with the same email or create a username that has previously been used.
Delete button added in 1.2.7.1 release, available now for download.
In order to delete a user, you first need to suspend him. After a user is suspended, a new “delete user” button will be shown.
