A clan can be started by anyone but must have 3 members already to start it. Once you have three people willing to start one the leader has to send me an email with the clan name and the three other members. You can make your own rankings for your clan. For example:
Leader - Hippo
Second in command -
Knight -
Knight -

A clan starts with 0 Niks in there account, but members can donate Niks for that. Clans have a limit of 8 members.
