Hi since the last patch i have yellow brackets in front of my name i presume for clan tags, but i cant find any where to add my clan tags can anyone help?

I think you need to use MassTumor's EL!TE trainer.

Be carefull though, as it might cause this.

Sorry i dont mean in my title but on the scoreboard.

When you use it you will gett he clantag, which should then be supported on the scoreboard since the newest revisions.
