Hi. Thanks for this awesome plugin - it's really fantastic. I have run into one issue that might be problematic for us though and would like to get some feedback on it.
In the Statistics Overview section, the default is to show all users (when 'Show only users, who solved the quiz' is not clicked) - not just from the site that the plugin is activated for but for all users in the WPMU installation!
So any admin who uses this plugin can see both the usernames and publicly displayed names from every site? This could be problematic for privacy issues.
Are there any plans to restrict the users shown on the list to those within the site?
