Add "sponsored goodies". Enable players to send a gift to another player in the form of a donation towards a few weeks of goodies. You can buy many weeks for your 4th character while many players are without the means of donating.
Doing so will
1) Finance the game
2) Create more characters
3) Make both parties happy 
Tom is interested given some minor tweaks to the suggestion, the thread talking about it is now on the Feature Request board.
