Add four subpoints at the end of the tutorial:
- join a combat clan
- message a clan
- post on clan wall
- receive a chatmail from a clanmate
First one would reward you with more CB$ that it generally costs a relatively new player to join the clan.
Second and third would reward you with EXTRA BA !!!
Last one would reward you with whatever you deem most appropriate.
Also, add a new feature to clan leaders : INVITE NEUTRAL PLAYER TO CLAN.
This would (temporarily) act as if the target player would have already joined the clan (from a clan max MPR you can accept standpoint), as long as the invite stands (i.e. until target joins a clan, not necessarily yours) or until the invite is rescinded.
