What is a clan tag, you ask? Why on earth should I give a crap? Well, its a statement of steamtacular fabulousness, that can only be claimed by epics! Simply change your username on steam, by clicking View Friends List, bottom right, and then the drop down arrow by your name! All you have to do, is put [TES] before your name! this identifies you to fellow epic gamers, making it easier to put together Epic Games! Also, it inspires insipid questions from non epics about your clan tag, and and what it stands for, and when they inevitably ask if they can join, you can tell them no, only cool people are epics :P
