In the French version, the extension works well, except one thing : as the administrator, I can't find "Using a new option in "general forum settings", administrators can also set specific forums so that new topics will be automatically subscribed by their authors." as shown in hereafter attached screen copy. Maybe I'm wrong, but I'm not sure that my forum members can use this extension even after having answered "yes" via their User Control Panel (as shown in your 1st screenshot)...

Best regards,
Pierre Antier
