Hi there @HELLOxFRIEND
You're re-opening an 8 years old topic here... Might have been the confusion with the time stamp displayed on the topic prehaps, Aug 11 doesn't means actual 11th of August but August 2011 .
Next to that, if you click on the avatar or user name in a post, you will have a popup window with the user name profile, clicking again on this window will display the Profile Activity page and from there you can see information like Last Post & Seen. In this case this user wasn't active since 2013, so really a dead topic here.
Hope that helps for browsing & reading on the forums
