Yell's demands are that:
- the Yellowikis site is shut down
- control and ownership of the domain name is passed to Yell
- compensation is paid to Yell for loss of profits
- the founders agree never to set up another competitor to Yell
Is this another attempt by a company to claim trademark of a generic word or part of one (Yellow/Yell) and prevent it's use (like Microsoft and Windows), or is Yell just using any excuse to drive out a competitor?
