Hey Sky, welcome to the forums! All you need to do now, is join the “SYN New Dynasty” usergroup. I will include the “Join A Clan” link to make things easier for you.
Once you click on the link, locate “SYN New Dynasty” on the list. Click the “Join Group” bubble on the right (ignore list members). Scroll down to the end of the list, and click on the button that says “Join Group” again. Let me know if you have any questions.
