To be given access, you need to request to join the usergroup. In your User CP, hit "Join a Clan" and then look for the XGC Nemesis XK clan. Select the join bubble/check then at the bottom of the page, hit the request/send/save button. After you do that, I get a request message and I will approve it. If you don't do it today, I probably won't get to it until sometime this weekend.
Congratz.
Game on.
