HAahahahahah!!!! it works!!! So i was pretty desperate to get a clan tag today and i began searching youtube for the clan tag changer that prpa made. I found one on mediaFire but it was set to private... Then i kept looking and thanks to help of google translator and common sense i found a video with another link to download the tag changer!! So it took me only minutes to figure out how to use it. watch this video and this is how i got my clan tag!
