Its pertinent to remember that MOST clans you join in the game are headed up by Player Leaders, so you need to find them to join their clans codedly.
If you follow the instructions (check boards, find out who is in charge, etc) and can't find the leaders, just remember that they cannot be online all the time. If, after a few days, you are still struggling to find someone, you can also send a Request through the Request Tool on the main site and ask staff for assistance.
You can also ask for more character-specific information through the Request Tool, because we try to avoid linking a Board Personality with an In Game Character as much as we can.
