Ask yourself..
1)Will there be type-in traffic?
2)Is the name catchy?
3)Is the name easy enough to spell for the dumbest of people to remember?
4)Are there any companies/individuals that you could sell the name to right now?
The more negative your answers, the less it's worth.
If you don't like your answers, then..
1)Grace delete
2)Sell it within a bundle of sites
3)Develop it! You CAN make it worth more. Check out the others sections on NamePros.
