I have changed my handle from DarkAssassin to this([[user:emotionless]). I changed it yesterday night. I want that none will find me in DarkAssassin. But still handle exist. And also I not able to login in DarkAssassin handle. Can I completely remove my DarkAssassin account so that none can find me in DarkAssassin handle? And in others sites I used DarkAssassin as my handle name. Thanks :)
From announcement page
So it's kind of feature
UPD: On the other hand it seems it doesn't work yet(tested with my old nick), so it seems I was wrong
Thanks riadwaw for your comment. So it means that I have to wait. Thanks again :)
