Just found out about this plugin via Jeff and interested in trying it out so have signed up for an API key :)
Was wondering if you would consider:
1. Updating the url of the BruteProtect logo for the admin interface - mine currently links to BruteProtect-Logo-Text-Only-75.png but this does not exist in the folder (only 40)
2. Adding a blank index.php to the plugin folder to prevent directory listing?
