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as long as the invite stands (i.e. until target joins a clan, not necessarily yours) or until the invite is rescinded.
